Pimli Prentiss born Paul Prentiss, was the warden of Algul Siento. He was tall, overweight, and balding. Prentiss he adopted the taheen name Pimli during his induction ceremony, after being recruited by the Crimson King to run the Devar-Toi, the Crimson King's prison for Breakers. He got the job by replying to a help wanted advertisement in a daily newspaper. Pimli did not reside in the universe in which Algul Siento existed, but a parallel Earth very similar to Keystone Earth, where he worked as a prison guard.
