Into the Outside
The Ninth World is surrounded by gateways to strange dimensions left behind by earlier civilizations. This supplement presents ten transdimensional locations, including worlds where travelers exist in multiple places, become living sound, split across time streams, or alter reality through thought. It details several methods of dimensional travel, new creatures such as the arravelon, pariall, time wraith, and lycidaris, and twelve alternate realities with distinct environments, dangers, and inhabitants. Adventures can explore places such as the Banded Bluff, the Whispering World, Celerillion, and Reeval, the source of the Nibovian threat.
