Zangetsu

Zangetsu: Half-Drow HexBlade, "Dark Samurai"

There is a secret organization known as "The House of Shadows" (Working Title) they protect the veil between the material plane and the Shadow fell and when something gets through it is their job to hunt it down. Members of the House of shadows use dark magic to hunt that which is wicked. These Dark Samurais are trained in the art of shadow manipulation and are each granted a unique weapon called a "Zanpakuto". Zangetsu’s sword is able to capture the essence of evil creatures & demons he has slain. This stored essence can be released from the blade to cast powerful magic as well as temporarily summon creatures “bound” to the service of Zangetsu.
