The satellite planets of the gas giant Omen, as well as its largest coorbital: Gymnome, Eaurp Guz's homeworld and the setting of Train Puzzle dot exe.
Oldsky, Lake, and Rival are all also known to have life, with Oldsky having a biosphere that is as fully developed as Gymnome.
The orbits of the moons of Omen. The periods are +25.3 hours, +50.7 hours, -174 hours, +236 hours, and +628 hours. Notably, the largest moon, Oldsky, is an obviously captured satellite in a retrograde orbit, but it is thought that Rival and Wanderer are captured satellites as well, with the only surviving original moons of Omen being the three dead-comet-like inner regular moons, which have 7-10 hour periods, as well as Spark and Lake, though the latter have likely been altered at some point in their history by collisions with protoplanets from the inner Zwo-nmu Star System.
