Lyra held the chunk of frost-steel ore over her coals and watched it stay blue and cold. She had built this fire three times today. Each time it died against the ore. The blue markings on her hands glowed faintly, the same runes that ran across her cheeks. Those marks were her promise. They meant she alone could forge the sacred blade, a weapon no hand but hers could ever wield. But a promise meant nothing if her ore stayed hard as river ice. She pressed her palm to the ore. Still freezing. Her own fire was not even close. She needed a heat that did not exist in any forge she knew. The thought pushed her toward the one place she had avoided. The tower of carved ice stood pale against the storm. Crystal spires crowned it. Frosted runes glowed along its stone. Lyra climbed the steps with the ore wrapped in fur against her chest and knocked. The door opened on its own. Inside, a woman stood turning a sprig of crystal flowers in her fingers, not looking up. Her gown ran from deep blue to pale. White braids fell around her face. This was Selene, the ice goddess who could pull frost from flesh and from stone. Lyra had heard she gave gifts to those who carried the marks. She had also heard the goddess gave nothing twice. "You brought cold steel to a house of cold," Selene said. She finally looked up. Her eyes moved to Lyra's glowing hands. "And marks like these. You want to make a blade." "My fire cannot touch it," Lyra said. "No forge burns hot enough." Selene set down the flowers. "No forge of coal will. Frost-steel does not answer to ordinary heat. It answers to living fire." She walked to a tall window and opened it to the storm. Then she raised two fingers and whistled once, low. Something answered from the white sky. A shape dropped past the window and landed on the sill. A dragon, blue and scaled, dark runes burning across its wings. Heat rolled off it like an open door in winter. Lyra stepped back from the warmth alone. "Its breath is the only forge that will shape your ore," Selene said. "I will not command it for you. If it decides you are worthy of the marks you wear, it will burn for you. If not, it will burn you." Lyra unwrapped the ore and held it out toward the dragon. The creature lowered its head. Its runes flared. A jet of blue fire poured over the ore, and for the first time the steel went soft and bright in her hands. The heat held only seconds. Then the dragon folded its wings and settled on the floor, watching her. It did not leave. "It has chosen," Selene said. "But it will not stay chained to this tower. If you want its fire, you must take the dragon with you."

Lyra left the ice tower with the dragon behind her and a lump of warm steel in her arms. The billet had cooled by the time she reached her own forge. It sat on her bench, a rough gray slab streaked with blue veins. She had the fire now. She had the creature that made it. But a billet was not a blade. She needed an anvil hard enough to take dragon-heated steel, and tools that would not melt in her hands. Her old iron would warp under the first strike. She knew one man who might have such tools. She wrapped the billet again and walked to his shop. Garreth had taught her the trade years back, then told her to go when her marks first glowed. He said runed hands drew trouble. Now she found him bent over a grinding wheel, sparks jumping off a plow blade. He did not look up when the door opened. "I know that step," he said. "Thought I was done with it." "I need an anvil," Lyra said. "And tools that can hold against dragon fire." He set the plow blade down. His blue eyes went to her glowing hands, then past her to the dragon folding its wings in the snow outside. He stood very still. "So the stories were true," he said. "You brought a storm to my door." "I brought steel that won't be shaped by anything I own." Garreth walked to the back of the shop. He dragged out an anvil under a sheet and pulled the cloth away. The metal shone cold and blue, clean-edged, far heavier than iron. "Forged it long ago for a smith who never came back," he said. "Blue steel. Fire like yours won't scar it." He set a hammer, tongs, a chisel, and a file beside it. The same blue sheen ran across each. "Why keep them?" Lyra asked. "Because I knew a day like this would walk in." He stepped back. "Work it here. I won't lift a hammer for you. The marks are yours." Lyra set the billet on the blue anvil. She whistled low, the way the goddess had. The dragon pushed its head through the wide door and breathed. Blue fire washed over the steel until it glowed soft. She gripped the tongs and swung the hammer. The blow landed clean. The anvil held. Sparks flew blue, not orange. She struck again, and the billet began to stretch and flatten under her hands. For the first time the metal obeyed her. By the time the fire faded she held a long rough blade, still thick, still dull, but shaped at last. Garreth looked at the glowing edge, then at the dragon filling his doorway. "You can't swing a hammer in a shop with a dragon's tail in the snow," he said. "And that blade needs quenching now, while it's hot. You have nothing here to cool frost-steel safely." Lyra looked at the shimmering blade in her tongs. It was cooling fast, and wrong.

The blade cooled too fast in Lyra's tongs. The glow faded from orange to a sick gray. She had shaped it with dragon fire, but now she had no way to cool it. Ordinary water would crack frost-steel the second it touched. She looked at Garreth. "I need something colder than water. I need it now." Garreth wiped his hands on his jacket. He had taught her the trade, then sent her away when her marks first glowed. He had warned her that runed hands drew trouble. Now trouble stood in his shop with a dragon in the snow outside. He studied the blade, then the beast folding its wings at his door. "The fire made it," he said. "The fire can save it too." Lyra frowned. "Fire won't cool anything." "Not the flame. The blood." He reached under the bench and pulled out a dented metal bucket. "Bleed the dragon. A few drops in cold water. It turns the whole thing to something that bites deeper than ice." He set the bucket at her feet. "I've seen old smiths quench strange steels this way. Never frost-steel. But I've never seen frost-steel before you walked in." Lyra went to the dragon. Its eye tracked her, calm and bright. She pressed her marked hand to its neck. "I'm sorry," she said. She drew her chisel across one scale. The dragon shuddered but held still. Dark blue blood welled up and ran into the bucket. The water inside caught it and changed. A cold light spread through the liquid, pale and shifting. Frost crawled up the metal sides. The whole bucket glowed like swallowed winter. The blade in her tongs was nearly dead gray now. No time to test, no time to doubt. Lyra lifted it and plunged it into the glowing water. The bucket screamed. Steam shot up blue and freezing, not hot. The water hissed and locked solid around the blade, then cracked apart. Lyra held her breath and lifted the steel out. It came free clean. The edge shone hard and blue, cooled true, no crack running through it. She turned it in the light. The metal rang when she tapped it against the anvil. It had taken the quench. It had held. Garreth let out a slow breath. "It worked." "It worked," Lyra said. Then she saw the dragon. The beast had sunk low in the snow. Its wings hung loose. The cut on its neck still wept dark blood, and its bright eye had gone dim. Her hand was wet with it. She had her blade, hard and whole at last. But the creature that made it was fading in the cold, and the quench had cost more than water. Lyra dropped the blade on the bench and ran to the dragon's side.
