From publisher blurb:
With a familiar yet different set of rules, Crimson Blades gives you fantastic old school-style dark fantasy/sword & sorcery role-playing. You can be a brooding sorcerer with a demon blade, a savage barbarian with an equally savage panther companion, a grim tomb-robber seeking the riches of a long-dead empire or even a Dendrelyssi - one of the last members of a decadent race of necromancers looking for redemption in the lands they once ruled.
Included in the game are five human character classes: Barbarian, Fighter, Mountebank, Sorcerer and Thief plus the inhuman Dendrelyssi and the NPC class Royal Redeemer. There are the traditional rules for spell-casting as well as rules for summoning and binding demons, elementals and undead. Included in the game is a brief setting "The Crimson Lands" for you to use as the basis for your own campaign.
