The Three Kingdoms Wiki

Welcome to The Three Kingdoms, a D&D Campaign setting. The setting was created by D,G, Redd in the before-time to serve as a world in which to play Dungeons and Dragons in a play-by-post forum format. Subsequently, Redd has used it as a backdrop for several novels and stories.

Dungeons & Dragons 3.5e is the nominal game edition used for the setting, but it's just numbers so you can adapt it whatever you like.
