You meet "the Attendant upon the Red Throne".
Everyone you encounter in Carcosa has a ridiculous title.
This site was created by Ramanan Sivaranjan. The layout borrows heavily from the look and feel of the Carcosa hardback available from Lamentations of the Flame Princess. Geoffery McKinney is currently publishing adventures under the name Psychedelic Fantasies, and they are also quite enjoyable. If you like this site, you might also enjoy my D&D blog, Save vs. Total Party Kill.
