Ubla

The winged girl’s home — more a moon than a planet, where all inhabitants are winged humanoids and no animals exist. Broke in half after an asteroid attack.

Described as more likely a moon than a true planet. All inhabitants are humanoid with wings; no animals exist on Ubla. Its time system runs faster than Earth’s — their “2026” equals Earth’s “2024.” Attacked by a swarm of living asteroids and broke in half — one half had all the civilization, the other had all the stores; still livable and orbiting normally after the split. The name “sounds like a normal name in their language; in ours it sounds silly.”
