Starting Points

The realms beyond the one of mortals vary from setting to setting. Pits inhabited by demons or other fiends, the underworld where the dead go, dream realms inhabited by fey creatures, eternal storms of elemental energy and the realms of the gods. And beyond that are realms that make no sense, alternate realities or weird places that operate in rules beyond comprehension.

Adventures set in these realms tend to be at a higher power level, as characters face powerful creatures and godlike beings, and must survive these very realms too.

Also of interest will be the Random Tools Guide for Planes Beyond. Finally for more PDF titles try Random Table Titles for Fantasy.

Major Titles

Some PDFs are much larger and comprehensive.

Castle Oldskull - 333 Realms of Entropy from Kent David Kelly is filled with tables for creating realms by a dominant terrain, with some examples of these planes.
For other planes the Plane Maker from Ennead Games makes total sense. Filled with tables about the plane, what inhabiteds it and how to get there. Depending on your planar adventures, Deities and Pantheons may also be of interest.
A Rough Guide to the Pit from Arion Games details demonic realms for Fighting Fantasy, but easily used in other games. It has tables for creating demonic planes and encounter tables.
