They called it the Nexus Dragonhorn AIO at the edge of the grid: a compact, humming artifact that somehow felt older than the city and younger than the coming dawn. It fit in your palm but carried the weight of satellites, symphonies, and a hundred clandestine conversations. People used the acronym like a prayer and a joke—AIO: all-in-one, all-in-oneiric, all-in-oneirically impossible. Whatever it truly was, it blurred the line between tool and oracle.
