Wraith: The Oblivion is a complex and rewarding game, arguably the most original contribution that White Wolf has made to the roleplaying genre. Most uniquely, Wraith develops an entire world with its own distinctive metaphysic and environment. The Underworld is a distinctly alien environment and one that requires some experience with (both as a player and as a character) to understand. With that in mind, it seems appropriate to contribute some kilobytes on the materials of the Underworld and how not to think of them.
