The Guardian Islands

Kept by the Seven Guardian Tribes since the deep past, and left largely alone by the present-day hunt for the Good Luck Cats — not part of Catelonia, or any other named realm, an archipelago of its own. Each of the seven tribes holds one island: the Landing, the Mines, the Rookery, the Terraces, the Wake Site, and more, each guarding its own share of rare materials and older secrets.

The islands are the reason the Guardians exist at all — raised by Neterios to keep the ancient listening network running, tribe by tribe, long before there was a Heliopoly to guard.
