Darok (Klingon)

Darok was a Klingon male and the gin'tak of the House of Martok. Darok's exact age is unknown, but he was a member of the Klingon Defense Force by the mid-23rd century.

Early life
Darok's mother was also a member of the Defense Force and fought against the Romulans, in a battle where she was killed. Years later, Darok would express regret that he did not talk to his mother before she left to fight the Empire's old enemy. (The Left Hand of Destiny)

His father was killed when a ship crashed into a brothel he was frequenting. (The Left Hand of Destiny)

Darok had once fought against Captain Matthew Decker on a planet after Darok's ship and Decker's Constitution class starship had exchanged fire and fought on the planet's surface. Decker managed to shoot Darok in the leg, but later patched the wound and signalled Darok's ship to beam him aboard. (The Left Hand of Destiny)

Dominion War
As the House of Martok's gin'tak, Darok accompanied Martok to Deep Space 9 during the Dominion War and also served as his assistant on the space station and aboard the IKS Ch'Tang. Darok became friends with Kor when the latter was assigned to the same ship, with both reminiscing about the Empire of old. (DS9 episode: "Once More Unto the Breach")
