Dreamden (5E)

From publisher blurb: Dreamden is debauchery disguised as enlightenment. Here, wealthy aristocrats exchange gold for false visions, misplaced purpose and distorted truth. In return, they invariably go mad. Promoted as a rustic resort, Dreamden provides rich city-dwellers the opportunity to get in touch with their more primitive side. Here, the wealthy aristocracy feign connection with their ancestors and, after smoking a range of exorbitant narcotics, go on self-aggrandizing sprit quests. The whole thing is a scam, run by an enchanting elf named Dreamer. As customers stumble about in a stupor, Dreamer syphons their mental energies to feed the demon-king to whom he is indebted. Dreamer guides the dreams of his clients, introducing them to highly addictive substances and securing their life-long annual patronage.
