J'rgan was a male Klingon serving in the Klingon Defense Force in the 23rd century. His father was a follower of Kahless's teachings on honor during a time that those teachings were unpopular in the empire, and he impressed those teachings on his son. As an adult, though, J'rgan rejected these teachings, and as a member of the KDF, agreed to act as a spy for those who would pay him for information on his superiors.
