The Cult of Orcus
[Taken from the Dungeon Master’s Guide]
The Guardbury Downs take their name from this striking ruin, a large monastery that has lain in ruins for almost one hundred fifty years. The abbey was dedicated to Bahamut and served as the base of a militant order of paladins who won great fame fighting in Nerath’s distant crusades. As the story goes, the paladins brought a dark artifact back from a far crusade for safekeeping, and evil forces gathered to assault the abbey and take it back. Extensive dungeons lie beneath the ruins, which might still conceal the hoarded wealth of the old crusading paladins.
