The Memory Vault wasn't marked. Just a bump on the ice. A concrete dome, half-buried. One steel door. No handles. No keypad. Just metal. "This is it," Elena said. The wind ate her words. She had the emitter on her back now. A gray box. Looked stupid. Her mother was back on the boat. We just had guns. And us. "How do we get in?" Kenji asked. He stared at the door. Borealis's notes said look north. A maintenance door. We found it. Smaller. Iced shut. Caiman dug at the ice with his knife. I worked the frozen lever. It cracked loud in the quiet. The door opened to a tunnel. Sloped down. Cold, but not outside cold. A dead cold. Smelled like nothing. We went in. Single file. Boots echoed. The tunnel ended at another door. It opened into the vault. Wasn't what I thought. No servers. No tank
