Cag was a 23rd century Stoyak man who served in security under the reign of the Great Uxorda.
History
Cag liked to play board games and sometimes had a sadistic attitude.
In 2266, Cag and fellow guard Dalik manned a security station responsible for overseeing the confinement of Spock and Netuya, who were locked in an underground prison cell after being captured by Colonel Knarg.
Cag lost 18 injas in a board game with Dalik and grew unsure of a move during the rematch. When Spock cried out, Cag grabbed a shock rod and approached the cell, but was grabbed and knocked unconscious by Netuya. (TOS comic: "A World Against Itself")
