Limbo's Layers

A lot of scholars like to talk about Limbo as having various layers, and they even name them, as if hiving them a tag will make them sit still and become a certainty. But the fact of the matter is, if Limbo does have layers, it doesn't respect scholar's boundaries at all. Sure, there are barriers a basher can encounter between one region of Limbo and the next, and there are paths through those barriers. But the barriers are never constant. Even if they were, the Limbo on one side of a barrier is much the same as the Limbo on the other, so there's not much point to them. Worse, the various realms and permanent cities generally ignore any barriers, being found one time on this side and the next time on the other.
So the pragmatist just treats Limbo as one vast layer, without worrying about why the barriers arise. And in that one vast layer lie all of Limbo's various realms, towns, and special features.

List of Realms and Sites

This Realm serves as a retreat and testing ground for solitary elves and a few human rangers who have found favor with Fenmarel Mestarine, the elven god of innocent scapegoats and outcasts.

Known as Slaadheim to the Ysgardians and the Urkrocl to the githzerai, the Spawning Stone is the primordial home of the slaadi race and the realm of the greatest dominion. each race of slaadi goes to the Spawning Stone in a sequence during the mating season (which looks like any other season in Limbo, but the slaadi always know it), and - while they are mating - currents of chaos-stuff flow toward the stone. Sages believe that the pure chaos matter of Limbo is the food of the young slaadi. Massive tidal waves and whirpools roll out from the Stone for hundreds of miles around when the eggs are hatched.
One death slaad guards the Spawning Stone at all times, and this creature can use the powers of the Spawning Stone as if it were an anarch with complete mastery of chaos-stuff. Some say that anyone who wrests the control of the stone from the slaad gains the same powers: others say that captured stone would simply melt back into Limbo and the slaadi would conjure up a new Spawning Stone somewhere else.

List of Towns

This is the githzerai's largest city, with a population estimated at 2.000.000 persons. Not surprisingly, it's primarily a military stronghold, designed to be the race's final defensive point should their enemies ever invade Limbo en masse. That such a "last stand" location exists is not so much a matter of necessity, but rather an eloquent statement about the githzerai mindset.

This is the "religious" centre for the githzerai race. They don't have priests, but instead revere their fighter/wizard god-king, and under his careful eye study the magical arts. Thievery is also revered in this city, apparently because it teaches skills useful for acquiring information outside githzerai settlements, and for infiltrating githyanki strongholds. Consequently, the githzerai "god-king" has integrated a respect for thievery into the peoples worship of him.

This little halfling village could best be descirbed as quaint. It's also known as a place of great hospitality, despite the fact that its guests must sleep out in the open.
