Finli O'Tego was the Chief of Security at Algul Siento. He was a taheen with the head of a weasel, which earned him the derisive nickname of "The Weasel". He considered the pus from a pimple to be a delicacy. He was good friends with Algul's warden, Pimli Prentiss. He prides himself as being one of the few taheen able to read and appreciate human literature. It is also possible Finli was related to Humma O'Tego, Algul's previous warden.
