Ennatum

Ennatum was a nobleman of Uruk. He and Gudea, resentful of Gilgamesh's arrogant and dissolute behavior, sent their king on a spying mission to Kish, then sent word of his coming to Dumuzi. The plot failed when the Seventh Doctor and Ace helped Gilgamesh against his attackers, and Ennatum had Gudea killed with poisoned beer to keep him silent. (NA: Timewyrm: Genesys)
