The entrance to the Obsidian Spire was a cavern of black glass and polished stone. It felt like walking into the throat of a great beast. There were no torches or lamps to greet us. Instead the walls themselves seemed to bleed a faint violet light that did not provide any warmth. It was a cold glow that made the shadows in the corners look deeper and more alive. I kept my hands clenched at my sides to keep them from shaking. I was a daughter of the sun and this place felt designed to swallow me whole.

"This way." Silas said.

He did not look back to see if I was following. He knew I had nowhere else to go. His footsteps made no sound on the marble floor. I on the other hand felt like every step I took was a drumbeat in the silence. The heat from my skin was already fighting the unnatural chill of the hall. I could see the faint trail of steam rising from my damp clothes.

We passed through a set of massive iron doors that opened without a sound. Beyond them lay a staircase that spiraled upward into the darkness. The air grew thinner and colder as we climbed. I felt the weight of the stone above us pressing down on my chest. It was a physical pressure that made it hard to catch my breath.

"How many people live here?" I asked.

My voice echoed off the walls. It sounded small and fragile in the vast space.

"As many as need to." Silas replied.

He reached the top of the stairs and paused at a landing. He turned to look at me with those piercing silver eyes.

"This level is yours." Silas said. "You will find everything you require for your comfort."

He gestured toward a set of double doors carved with patterns of frost and thorns. He pulled a heavy iron key from his pocket and held it out to me. Our fingers brushed as I took it. The contact was like a shock of ice water. I flinched but I did not drop the key.

"Am I to be locked in?" I asked.

I gripped the cold metal tightly. I looked at him and waited for the lie.

"The lock is for your protection Elara." Silas said. "Not all of my subjects share my patience for the Fae. Some of them would prefer to drain you dry tonight rather than wait for the warmth you promised."

He stepped closer to me. He was so tall that I had to tilt my head back to see his face. He smelled like winter air and something ancient.

"You are a precious resource now." Silas whispered. "I suggest you treat yourself as such."

"I am a person." I snapped. "Not a bag of grain or a pile of coal."

"In this city those things are more valuable than gold." Silas said. "Sleep well Little Sun. We begin your work at dawn."

He turned and vanished back down the stairs before I could argue. I stood alone on the landing for a long moment. I listened to the silence of the tower. It was not a peaceful quiet. It was the heavy silence of a place that was holding its breath.

I pushed the key into the lock and turned it. The mechanism was smooth and heavy. I stepped inside the room and gasped. It was a suite of rooms larger than my entire cottage back home. There was a massive bed draped in black furs and a fireplace made of white stone. Huge windows stretched from the floor to the ceiling. They looked out over the sprawling dark city below.

I walked to the window and pressed my hand against the glass. It was freezing to the touch. Below me the City of No Stars looked like a graveyard of light. The blue neon flickered in the distance but most of the streets were shrouded in shadow. I could see the faint outlines of the slums where the poorer vampires lived. I thought about the children I had seen in the street.

I turned away from the window and walked to the fireplace. There was no wood in the hearth. There were no coals. It was just a cold empty pit of stone. I knelt down and placed my hands on the base of the chimney.

I closed my eyes and reached deep inside myself. I searched for the spark that lived at my core. It was smaller than it used to be. It was a flickering amber flame that felt weary from the journey. I whispered a word in the old tongue of my people. I pushed a sliver of that heat through my palms and into the stone.

A soft golden glow began to radiate from the hearth. It was not a fire of wood and smoke. It was a fire of pure essence. The stone warmed under my touch. The chill in the room began to recede. I watched as the frost on the windowpanes melted and turned into tears of water.

I sat back on my heels and watched the light. It was the only bit of home I had left.

A soft knock sounded at the door. I stood up quickly and wiped my hands on my skirt.

"Who is it?" I called out.

"Dinner is served Lady Elara." A female voice replied.

I walked to the door and unlocked it. A young woman stood in the hall. She was pale like the others but she had a kindness in her face that I had not expected. She carried a silver tray laden with covered dishes.

"My name is Mina." She said. "I am to be your attendant while you stay with us."

She walked into the room and set the tray on a low table near the fire. She paused when she felt the warmth of the hearth. She looked at the glowing stones and then back at me. Her eyes widened in surprise.

"It has been a long time since I felt a real fire." Mina whispered.

She reached out a hand as if to touch the warmth but she stopped herself. She looked at me with a mixture of awe and fear.

"Is the King always so cold?" I asked.

I sat down at the table and lifted the lid off one of the plates. It was roasted meat and root vegetables. It smelled delicious.

"He is the oldest of us." Mina said. "He has forgotten what it is like to feel anything else. He carries the winter in his heart so the rest of us do not have to."

"That sounds like a very lonely way to live." I said.

I took a bite of the food. It was seasoned with rare spices that made my tongue tingle.

"Power is always lonely." Mina replied. "The King does what is necessary for the survival of the city. He does not ask for thanks."

"He did not have to take me." I said.

Mina looked toward the door as if checking for listeners. She leaned in closer to me.

"He did not just take you to save the city Elara." Mina whispered. "The Obsidian Spire is cracking. The very foundation of our world is freezing over. If you had not come the tower would have fallen by the next new moon."

She stood up straight and smoothed her apron.

"Eat your fill." Mina said. "You will need your strength for tomorrow. The King does not like to be kept waiting."

She bowed her head and left the room. I heard the lock click from the outside. I was alone again.

I finished my meal in silence. I watched the golden light of my fire dance against the black walls. I thought about what Mina had said. The city was not just cold. It was dying. And Silas was the one holding it together with nothing but his own frozen will.

I walked back to the window. I looked out at the dark horizon. Somewhere out there the sun was rising over the Summer Court. My people were waking up to green fields and warm breezes. They were safe because I was here in the dark.

I placed my forehead against the glass.

"I will not let you break me Silas." I whispered.

The heat from my skin left a fog on the window. I watched it fade into the night. I went to the bed and curled up under the heavy furs. I did not blow out the light in the hearth. I let it burn. I needed to remember that even in the heart of the winter a single spark could stay alive.

I fell into a restless sleep. I dreamed of a forest made of glass and a king who was made of ice. In the dream he was reaching for me. He was not trying to hurt me. He was trying to keep from shattering.

I woke up when the first grey light of morning touched the room. There was no sunrise here. There was only a shift from deep black to a dull leaden grey. The fire in the hearth had gone out. The room was freezing again.

I stood up and dressed in a gown of heavy amber wool. I brushed my hair until it shone like polished copper. I was ready.

The door opened before I could reach for the handle. Silas stood in the hallway. He looked exactly as he had the night before. He did not look tired. He did not look like a man who had slept at all.

"It is time Elara." Silas said.

"Time for what?" I asked.

"Time to see if you are as powerful as your father claimed." Silas replied.

He turned and began to walk down the hall. I followed him. We did not go back to the Great Hall. Instead we went deeper into the heart of the tower. We descended a hidden staircase that smelled of damp earth and ancient magic.

The air grew colder with every step. My breath was a constant cloud of steam. I felt the fire in my core beginning to stir. It knew where we were going. It knew that something was waiting for us in the dark.

We reached a massive circular chamber at the very bottom of the spire. In the center of the room was a giant forge made of iron and gold. It was cold and silent. Chains as thick as my waist held it in place.

"This is the Heart of the City." Silas said.

He walked to the edge of the forge and placed his hand on the metal. A layer of frost immediately spread from his touch.

"It used to burn with the light of the first sun." Silas said. "It powered our lights. It warmed our homes. It kept the shadows at bay. But the fire died a hundred years ago."

He looked at me. His silver eyes were bright with a desperate intensity.

"I want you to wake it up." Silas commanded.

I looked at the massive forge. It was huge. It was a mountain of iron. I felt like an ant standing before a god.

"I cannot do that alone." I said. "My magic is not enough to light something this big."

"Then find a way." Silas said.

He stepped toward me. He grabbed my wrists with his freezing hands. He pulled me toward the forge.

"My people are dying Elara." Silas hissed. "The ice is coming for us all. Light the forge or we will all die in the cold."

I looked at him. I saw the fear behind the iron mask of his face. He was not a king. He was a man who was terrified of the dark.

I looked at the forge. I looked at the cold iron. I felt the fire in my heart begin to roar.

"Fine." I said. "But stay back Silas. You might not like the heat."

The basement of the Obsidian Spire did not just hold the Forge. It held the silence of a thousand years. I stood before the massive iron structure and felt the cold biting into my marrow. The air here was different than in my rooms. It was heavy and stagnant as if the oxygen itself had frozen in place. Silas stood behind me. He did not offer words of encouragement. He stood like a shadow cast by a dying world.

"Touch the iron." Silas commanded.

His voice was a blade of ice. It cut through the thick air of the chamber. I looked at the dark metal of the Forge. It was covered in a layer of permafrost that shimmered like crushed diamonds under the faint violet light of the wall sconces. The machine was a mountain of jagged edges and ancient runes. It looked hungry.

"It will drain me Silas." I said.

I did not turn to look at him. I kept my gaze fixed on the frost.

"A forge of this size requires a massive tithe of spirit. If I give too much too fast I will collapse." I explained.

"Then do not collapse." Silas replied.

I felt him move closer. He did not touch me but I could feel the vacuum of his presence. He was a void that wanted to be filled. He was a predator waiting for the first sign of a wound.

"You were sent here to serve a purpose Elara." Silas whispered.

His breath was a ghost of white mist near my ear. It made the small hairs on the back of my neck stand up.

"My city does not pay for ornaments." Silas continued. "It pays for results. The Council is watching the meters. The grid is failing in the lower sectors. Now light it."

I gritted my teeth. I reached out and pressed both of my palms against the freezing iron.

The shock was instantaneous. It felt like a thousand needles were being driven into my skin. The Forge was a hollow vessel and I was the liquid fire it had been waiting for. It felt my heat and it began to pull. It was not a gentle draw. It was a violent suction that tugged at the very center of my chest. I felt the amber spark in my core flare up in a desperate attempt to defend itself.

"Argh." I gasped.

My knees buckled. I felt my energy flowing out of my arms and into the dead machine. A dull orange glow began to throb deep within the iron belly of the Forge. It was weak. It was pathetic. It was a flickering candle in a vast dark cathedral.

"Is that all you have?" Silas mocked.

I looked up at him through the strands of my copper hair. He was watching me with a look of bored detachment. He did not care that I was shaking. He did not care that my skin was turning a sickly pale shade of grey. To him I was a utility. I was a tap to be turned until the water ran dry.

"I am trying." I wheezed.

"Try harder." Silas said.

He stepped forward and placed his hands over mine. He pressed my palms harder against the biting iron. The combination of the hunger of the Forge and the unnatural cold of Silas sent a jolt of pure agony through my nerves. It was a collision of extremes. I was caught between a frozen god and a starving machine.

I screamed. The sound echoed off the obsidian walls like a wounded animal. I pushed every bit of my will into my hands. I stopped trying to hold the fire back. I let it flood outward.

Suddenly the orange glow brightened. A roar of heat erupted from the center of the Forge. The chains rattled against the stone floor. The very foundation of the Spire began to vibrate with a low rhythmic thrum. For a single second the room was filled with a blinding golden light that chased away every shadow.

Silas did not pull away. He watched the light with an expression of hungry fascination. The heat should have blistered his skin. It should have turned his fine wool coat to ash. Instead he seemed to drink it in. He looked like a man who was seeing the face of a god for the first time.

The light died as quickly as it had come. The Forge went back to a low steady hum. The golden glow faded into a dim copper pulse.

I fell back onto the cold stone floor. My lungs burned as if I had inhaled smoke. My hands were red and raw from the cold and the friction. I could feel the fire in my core flickering like a candle in a hurricane. I was empty. I felt like a hollow shell washed up on a dark shore.

Silas looked down at me. He did not offer a hand to help me up. He did not even look concerned. He looked at the Forge which was now radiating a faint dormant warmth. He looked at his own hands. They were smoking slightly from the contact. He flexed his fingers as if feeling life in them for the first time in centuries.

"It is a start." Silas said.

He adjusted the cuffs of his shirt as if he had just finished a mundane chore.

"You will return here every evening." Silas said. "You will feed the Heart until the city streets glow. You will push until the frost on the Spire melts. If you fail to meet the quota I will find other ways to extract what is owed."

"You are a monster." I whispered.

I managed to push myself up into a sitting position. My arms felt like lead. I glared at him with every ounce of hatred I could find in my depleted soul.

"I am a King." Silas corrected.

He stepped closer until the toe of his boot brushed my skirt. He looked down at me with a cold pitiless gaze.

"And you are my property until the debt is settled." Silas continued. "In the Summer Court you were a princess. Here you are a spark in the dark. Do not forget your place again Elara."

He turned and walked toward the stairs. His coat swished against his boots with a crisp sharp sound.

"Mina will bring you something for the pain." Silas said without looking back. "Be ready for the gala tomorrow night. I want the aristocrats to see exactly what I bought. I want them to know that the winter is ending because I willed it so."

I watched him disappear into the shadows of the stairwell. I touched the stone floor and felt the lingering warmth I had left behind. It was small but it was there.

I lay back on the cold floor and closed my eyes. I was not just a debt. I was a weapon. Silas thought he had bought a battery but he had brought a sun into a house made of glass. One day I would find the strength to turn this heat into a fire that would melt his frozen heart into nothing but a puddle of regret. I would burn this city to the ground before I let him take everything I was.

I waited for Mina in the dark. I listened to the Forge. It hummed a low dark song that sounded like a warning.

I was a Summer Elemental. I was built for the light. But as I sat in the darkness of the Spire I realized that fire did not just bring life. It also brought destruction. I looked at my red raw hands and made a silent vow.

I would give Silas his warmth. I would give him all the heat he could handle. And when he was finally warm enough to feel pain I would show him exactly what happens when you try to cage a star.

The morning after the extraction felt like waking up inside a block of ice. My muscles were stiff and my palms were a map of raw red welts from the frozen iron of the Forge. I lay in the massive bed and watched the grey light struggle to penetrate the heavy glass of the windows. There was no birdsong here. There was only the low hum of the Spire and the distant sound of the city waking up in a state of permanent twilight.

Mina entered the room without a sound. She carried a jar of translucent green salve and a dress that looked like it had been spun from liquid gold. She saw me staring at the gown and offered a small sympathetic smile.

"The King requested you wear this for the gala tonight." Mina said.

She set the dress on the foot of the bed and walked over to me. She took my hands in hers with a gentle touch. She began to apply the salve to my burned palms. The cooling sensation was immediate and I felt a shudder of relief ripple through my body.

"He wants me to look like a sun." I said.

My voice was raspy and dry. I pulled my hands back as soon as she was finished.

"He wants everyone to see that the Summer Court has paid its debt in full." Mina replied.

She began to move about the room and gathered the things for my bath. She poured a vial of scented oil into the steaming water. The smell of jasmine and sandalwood filled the air. It was a cruel reminder of the gardens I had left behind.

"Is he always this cruel Mina?" I asked.

I stepped into the tub and let the hot water soak into my aching joints. I closed my eyes and tried to remember the feeling of the real sun on my face.

"Cruelty is a luxury for those who have a choice Elara." Mina said.

She began to scrub my back with a soft cloth. Her movements were practiced and efficient.

"The King does not believe in luxury." Mina continued. "He believes in the machine. He believes in the walls that keep the frost out. To him you are a part of that machine now."

"I am a person who can feel pain." I snapped.

I splashed the water in frustration. The steam around the tub grew thicker as my temper flared.

"He knows you feel pain." Mina whispered. "He just thinks it is a small price to pay for the survival of millions."

I spent the rest of the day in a state of quiet dread. I watched the grey light turn back into the deep violet of the evening. The city below began to sparkle with the new light I had provided. I could see the streetlamps glowing with a steady amber pulse. It was a beautiful sight but it felt like I was looking at my own blood spilled across the pavement.

When it was time to dress I stood before the tall mirror. The golden gown was strapless and clung to my curves like a second skin. It was woven with tiny enchanted filaments that captured the natural heat of my body and turned it into a soft radiance. I looked like a goddess of the harvest trapped in a world of bone and ash.

"You look breathtaking Lady Elara." Mina said.

She fastened a collar of white gold around my neck. It was heavy and cold. It felt like a leash.

"I look like a trophy." I said.

I touched the metal of the collar. It was cold against my skin.

"Then be a trophy that bites." Mina suggested.

A knock sounded at the door. One of the guards entered and bowed low.

"The King is waiting for you in the ballroom." The guard said.

I took a deep breath and followed him out of the room. We descended the central staircase of the Spire. The halls were no longer empty. They were filled with vampires dressed in the height of gothic fashion. They wore silks and velvets in shades of midnight blue and blood red. They stopped and stared as I passed. I could hear their whispers following me like the rustle of dead leaves.

"Is that the Fae girl?"

"She looks so warm."

"Look at her skin. It is actually glowing."

I ignored them and kept my eyes forward. We reached the massive double doors of the ballroom. They swung open to reveal a space of staggering opulence. The ceiling was a dome of black glass that reflected the flickering light of a thousand candles. An orchestra was playing a slow haunting melody that seemed to hang in the air like smoke.

Silas stood at the far end of the room. He was surrounded by a group of older vampires who looked like they were made of stone and spite. He wore a black suit that fit his broad shoulders perfectly. He looked up as I entered. His silver eyes locked onto mine and I felt a jolt of electricity run down my spine.

He broke away from the group and walked toward me. The crowd parted like water before a shark. He stopped in front of me and reached for my hand. He bowed over it but he did not kiss my knuckles. He simply held my hand in his freezing grip.

"You are late Elara." Silas said.

His voice was low and smooth. It carried a warning that only I could hear.

"I had to wait for the burns to stop stinging." I replied.

I pulled my hand back and tucked it behind my waist. I wanted him to see the defiance in my eyes.

"The price of progress is often discomfort." Silas said.

He offered his arm to me. I hesitated for a moment and then I took it. I did not want to cause a scene in front of his subjects but I made sure to keep as much distance between us as the arm would allow.

"Smile for the Council Elara." Silas whispered as we began to walk through the crowd. "They need to believe that you are happy to be here. They need to believe that the alliance is strong."

"I am not a very good liar Silas." I said.

I looked at the vampires we passed. They were all watching us with a mixture of envy and hunger. I saw a woman with skin as white as snow staring at my throat. She looked like she wanted to taste the heat in my veins.

"Then pretend you are an actress." Silas said. "The survival of your people depends on how well you play this part tonight."

He led me toward a raised platform where the Council sat. These were the oldest and most powerful vampires in the city. They looked at me with cold calculating eyes.

"So this is the Summer tithe." One of the councilmen said.

He was a withered man with a voice like dry parchment.

"She is smaller than I expected." The man added.

"She is powerful enough to light the Heart Vane." Silas said.

He tightened his grip on my arm.

"That is all that matters." Silas concluded.

"Is she stable?" Another woman asked.

She leaned forward and sniffed the air.

"She smells like she is burning from the inside out." The woman noted.

"She is under control." Silas said.

He turned me away from the Council before I could respond. He led me toward a balcony that overlooked the city. The cold air hit my face and I felt a moment of clarity.

"You talk about me like I am a dangerous animal." I said.

I stepped away from him and leaned against the stone railing.

"In this city you are a dangerous animal." Silas said.

He stood beside me and looked out at the lights.

"You are a creature of fire in a house of ice." Silas continued. "If you lost control you could melt the foundations of this tower in an hour. I cannot afford for you to be anything other than a tool."

"Is that why you wear the ice Silas?" I asked.

I looked at him. The moonlight caught the silver in his eyes.

"Because you are afraid of what happens if you feel a little warmth?" I questioned.

Silas turned to me. His expression was unreadable. He reached out and touched the gold collar around my neck. His fingers were so cold they felt like they were burning my skin.

"I am not afraid of anything Elara." Silas whispered.

He leaned in closer until our faces were inches apart.

"I have been dead for a thousand years." Silas said. "There is nothing left to melt."

"Then why are you holding your breath?" I asked.

I could feel the heat rising from my chest. I could feel the golden threads of the dress beginning to glow brighter. Silas did not pull away. He stayed in the heat of my aura. He looked at my lips and for a second I thought he was going to kiss me. I thought he was going to try and steal the breath right out of my lungs.

Suddenly a loud crash echoed from the ballroom. The music stopped. A woman screamed.

Silas was moving before I could blink. He pushed me behind him and drew a silver blade from the small of his back.

"Stay here." Silas commanded.

A group of vampires in grey cloaks had burst through the main doors. They carried jagged iron rods and their faces were twisted in a feral rage. These were not the aristocrats of the Spire. These were the rebels from the lower districts.

"The False King must fall!" One of the rebels shouted.

"No more taxes for the dead sun!" Another screamed.

They began to swing their iron rods at the guests. The ballroom turned into a scene of chaos. The aristocrats scrambled for the exits while the guards tried to fight back.

Silas turned back to me. His silver eyes were glowing with a predatory light.

"It seems my people are losing their patience." Silas said.

He looked at the rebels and then he looked at me.

"Show them what they are fighting for Elara." Silas commanded. "Give them a reason to be afraid of the light."

I looked at the chaos and then I looked at my hands. The heat was bubbling just beneath the surface of my skin. I didn't want to fight for Silas but I didn't want to die in this dark ballroom either.

I stepped forward and let the fire go.
