The Island's Side of the Story
Everyone in Neterios works. Catelonia is where they spend it.
If Heliopoly is where the exodus gets built and Planet 65 is where it gets mined, Catelonia is where it gets spent — the pioneers' Vegas. The Casino, the Feathers of Fury Arena, the Hapi bottling works turning out the energy drink that gets everyone through their next shift, twelve bird species that dive and strafe like fighter planes for sport and worse.
It's also, quietly, the most important island in the system: Omnibis keeps her temple here, watching the ledgers of every other realm from the one place nobody thought to look.
