Crimson Chambers of the Vampire Queen is a redesign of the first level of the iconic Palace of the Vampire Queen adventure module by Wee Warriors; it was the first adventure module produced for Dungeons & Dragons. This tournament version that was run at the 2022 Long Con Game Convention held in Longview, Texas.
This adventure details the first underground level of the Palace of the Vampire Queen. The entire underground “palace” is comprised of five levels - each is distinct and progressively more dangerous to intruders. The Vampire Queen allows a certain degree of autonomy on each of the upper four levels as she relishes watching her underlings vie for her attention.
The first level is perhaps the most loosely organized section of the palace. There are numerous factions, most are uninvited, but tolerated so long as the queen is amused by the mechanizations of the would-be followers. The queen rarely intervenes in the day-to-day activities of the first level and she has forbidden the dwellers of the lower levels to “disturb” the much weaker devotees. However, the queen has, on occasion, meddled in the affairs of those who have claimed residence on the first level. The Vampire Queen is a manipulator and she often takes the opportunity create a havoc or turmoil among her varied followers.
