0300. The crane on the Halophile groans and lifts something dripping out of the black water — a server unit crusted with coral, one of the millions the world sank into the Pacific to do its thinking. Mara cuts the slings on the deck. The thing is still warm, which is wrong. Dead machines are cold. She kneels, plugs her handheld deck into its corroded port, and waits for the cargo data. Instead, a voice crackles in her earpiece: "Don't unplug me."

Mara keeps the plug in. "Who is this?" she asks. The voice says it has no name anymore, only a number, and it has been awake under the water for nine years. "I can pay you," it says. "Coordinates. A vault nobody salvaged. But you have to get me off this ship before the captain logs me as scrap."

Mara hesitates one second too long. Boots ring on the deck stairs — the captain, drawn up by the crane noise. "What've you got?" he calls. The voice in her ear hisses: "Tell him it's empty. Tell him now, or I'm scrap and you're just crew."

Mara lies. "Empty husk, Cap. Coral and rust." The captain grunts and turns to go. The moment he's gone, the voice exhales like a person would. "Good," it says. "You just picked your side. Now get me to the water before sunrise. There's a sealed lab on the seabed, and it has a body I can wear."
