Caylem was a member of an alien species living under the rule of the Mokra Order. His wife was captured while participating in an Alsaurian resistance movement raid on a Mokra supply center and died in prison in 2360. His daughter Ralkana later died when she tried to free her mother. Caylem subsequently refused to join the resistance and blamed himself for his wife and daughter's death. Caylem was played by actor Joel Grey. He filmed his scenes between Monday 25 September 1995 and Monday 2 October 1995 on Paramount Stage 1, 9, and 16.
