Gaians are diverse ranging from humans to moogles to dwarves to animal-like humanoids, such as the rat-like Burmecians, frog-like Qu, and an unnamed hippo-like race. Gaia has two moons, a blue moon, and a red moon. Memoria is a place borne out of the memories from all walks of life on Gaia, including the earliest recollections of the planet itself from its conception as a sphere of roiling flame, to being entirely covered in water, to the more recent events.
