Hidden in a gap between time and space, in the nexus between realms and universes, is a library. Its shelves are filled to the brim with tomes and books about one topic.

The Villains of the Multiverse.

For those who find the library, they can meet with its caretaker: Castor Cain. He will offer you a some tea and tell you everything you need to know about the villain of your choice, be they from the lands of Dungeons and Dragons, Pathfinder, the many Worlds of Darkness and every realm in between.

All of this information is categorized in one place using a system called the Dastardly Decimal System.

Join Castor Cain as he talks about one evil form or another, preparing the next adventurer – or would be conqueror – for their quest.
