Sutek was a male Vulcan in the 23rd century. He hailed from the Last-of-all-Cities on Darien 224, a lost colony stranded from the rest of the Vulcan people before the Logic-reformation.
In 2254 Sutek led a rescue party to assist a landing party from the USS Enterprise which was under attack by another faction of Vulcans from the colony. He promptly took them to the colony where they stayed as guests for some time. Whilst the Starfleet personnel were there he expressed disgust at what had become of the Vulcan people, comparing them to lap-Sehlats for the Humans. He took particular distaste in Spock.
Sutek and the rest of the Last-of-all-Cities colony were ultimately killed when they used a powerful psionic weapon which destroyed the planet. (EV - Cloak and Dagger comics: "Cloak & Dagger", "Cloak and Dagger, Part 2 of 2")
