Lords of Faerun
Cult of the Dragon
The Cult of the Dragon, also known as Keepers of the Secret Hoard or Wearers of Purple, was a semi-religious evil organization venerating undead dragons, or dracoliches, founded by Sammaster, a powerful wizard….The Cult acted as an information network for its draconian “masters”, brought gems and riches as offerings, and encouraged evil dragons to become dracoliches. Their belief was that dracoliches were destined to one day rule Faerûn and beyond.
The Cult is indeed a mad organization but is surprisingly effective in its devotion. Left to its own devices, however, a cell of cultists will take extreme measures in order to fund its lavish magical research. Banditry, caravan raiding, threats, extortion, blackmail, and worse are all viable tactics for these fanatics.
