Bones of the Companions invites only the bravest to save a city from damnation. The adventure is designed for mid to high-level player characters of levels 7 to 10. All character classes are useful though a paladin and cleric in the party would be advantageous. The adventure begins in a city, town, village or fortification and can be placed in any campaign setting.

Bones of the Companions takes the characters from the basement of a recently deceased cleric to a place where all Hell has broken loose. The adventurers find themselves engaged in a struggle with powerful creatures in a monolithic maze for the dead.
