The Realm

Due to whatever capriciousness of the gods, this plane was made in a very odd form. The world itself is shaped somewhat like a bowl, it's a gradual slope, but the result being: You can see to the rim of the world, with a bit of height and a clear day. Almost all water runs to the center of the world, and is carried back out to the edge either underground or by clouds. Storms, almost exclusively, move center to rim.

There are no stars; only The Eye of Heaven, which heats the world. The Eye of Heaven itself sits, unmoving, above the center of the world. This gives the world a very uniform climate variance, starting at the center, which was a blasted plane of glass and rock, and slowly cooling as you move towards the rim, where you have an eternally frozen tundra.

Night and day are caused by the moon, gradually fading in, in front of the Eye, and then fading back out again. The moon is made of some translucent material, allowing the Eye to filter though somewhat. Some property of the moon causes it to become opaque in a slow wave that travels back and forth in the course of a month, giving rise to moon phases.
