Boneyard

The Boneyard (AKA Pharasma's domain)
The Boneyard rests on a disc atop a spire. The spire rises out of the Maelstrom, through Axis and finally comes to rest in it's own empty, starless plane. The centerpiece is Pharasma's palace, where the souls of the dead are judged and sent on their way. Most souls are sent to one of the other eight planes, and those who worship Pharasma (or one of the other TN gods) are sent to join their palace staff.
Those who worship Pharasma poorly, or are false are buried in the Boneyard and their souls are used as a material to expand the disc.
"But what of the atheists, agnostics and the indecisive?" I hear a soul ask. Those people are left to set up their own afterlife. The afterlife for an atheist is a lot like the mortal one, except without hunger or pain. A bland afterlife for bland people. They've formed a rather large city, a pale reflection of Axis far below.
Why would you come here? Well, that's mostly explained, but there's one extra reason. The Boneyard is still close to the Astral plane. If one was strong enough and brave enough, a soul may sneak back into the land of the living.
