Suns, Moons, and Color Pools

Color pools are several massive dimensional portals orbiting Otherwhere, each leading to a different outer plane. Celestial light shed by a sequence of seven such color pools function as the Otherwhere's "suns," while nine such pools appear at night at distant "moons" in the Astral Void.

Each sun color pool takes 168 hours to orbit the demiplane, creating seven 12-hour periods of "days" and an equal number of "nights." Orbital periods for moons vary.
