First published in 1977, Tegel Manor is the oldest of “Haunted House” adventures in fantasy roleplaying, and probably the very first megadungeon ever published. The Manor is a sprawling edifice of 250+ rooms filled with tricks, traps, puzzles, monsters, and situations both humorous and horrific. The huge manor house has been the curse of its owners, the Rump family, for generations – no matter how many times they have tried to get rid of it, the ownership manages to come back to them.
