Planes, Worlds and Planar Travel - Midkemia Online Online Help
12.2 Planes, Worlds and Planar Travel
While it is theorized that there are numerous planes of existence in the Midkemian universe, it has never been a proven fact. However, the discovery of Rifts during the Riftwar has led to an awareness that many worlds exist in the universe - far beyond the reach of any means of conventional travel. With Rifts, travel between these distant worlds is possible (and even travel within the same world). However, with the destruction of the Great Rift at the end of the Riftwar, no permanent Rifts are currently in existence on Midkemia -- and thus travel to other worlds, including Kelewan, has been rendered impossible.
