Kleeg attended the council sessions which discussed the plight of Styra in the trinary star system 83 Beta, and was there at the beginning of Project Atlas, an initiative conceived by fellow councilor Lanugu.
In 2267, after the biomagnetic recording of Styra was stolen and being ransomed by Anzar, Kleeg motioned to the council that blackmail not be permitted, a motion immediately supported by vote. As a result, James T. Kirk was authorized to use any means at his disposal to recover Styra, except paying the ransom. Kirk captured Anzur using a Trojan horse ploy. (TOS comic: "The Hijacked Planet")
