The Well of Dragons was a citadel operated by the Cult of the Dragon in the canyonlands near the Sunset Mountains. The site was a legendary graveyard of dragons and historically many dragons would travel to the Well of Dragons to die. Cultists freed the shadow dragon guardian of the site and built a citadel where they carried out their activities which mainly involved attempting to transform dragons into dracoliches. The citadel was well defended as it often came under attack from treasure hunters and dragons angered by the cult's beliefs.
