Salvador Duke is a human adventurer and sell-sword trained in the Arcane Arts. He rather enjoys gambling and thus far doesn't seem to ever be too far from his gith adventuring companion, "Edna":http://www.obsidianportal.com/character/29061.
Edna is a Githyanki seemingly extremely adept at the use of a katana. She partners with "Salvador Duke":http://www.obsidianportal.com/character/29059 as a sellsword and planar adventurer. Otherwise, she is quite a somber character.
