Kai Len is a half-elven musician with the house band at Titania's Cabaret. He performs on both the guitar and the shamisen, a traditional stringed instrument from Cozovode. Off-stage, he's happy to admit that his name is really Cailen, and that he's lived in Diablotin his entire life - the exotic foreigner act is just a selling point which he cheerfully exploits. He presumes that his father was an elf, although he has no idea who he might have been. He says he is 34 years old, though he appears younger. He has medium brown hair and green eyes, and is quite charming and handsome.
