Cruelty of Drakes
The Cult of the Dragon
You know some basics of why you are in or going to the town of Greenest. And they seem to involve an organization known as the Cult of the Dragon (aka Keepers of the Secret Hoard or the Wearers of the Purple).
Rumors you have heard:
The Cult of the Dragon venerates dragons, evil dragons in particular, and specifically dead evil dragons. They reanimate the gargantuan corpses as powerful and fell dracoliches. The Cult acts as an information network for its draconian “masters”, brings gems and riches as offerings, and encourages evil dragons to become dracoliches. Their belief is that dracoliches are destined to one day rule Faerûn and beyond.
The Cult is active throughout the Realms, but is specifically powerful in the Cold Lands and the North, where dragons are particularly abundant. Cult member activities include gathering information on particularly rich caravans to be raided, stealing unique items to be offered to their masters, and leading raids against their enemies (who, in their minds, are all those who might oppose the rulership of the dragons).
