An Andorian Imperial Guard soldier who served under Commander Shran during the 2151 occupation of the Vulcan monastery at P'Jem, where the Andorians searched for a hidden listening post.
Keval appears in the first-season Enterprise episode The Andorian Incident. He is one of the small party of Andorian soldiers, led by Shran, who seize the ancient Vulcan sanctuary of P'Jem and hold its monks hostage.
The Andorians are convinced that the monastery conceals a long-range sensor array aimed at their territory. When Archer, T'Pol and Tucker arrive on a courtesy visit, Keval and his comrades take them prisoner as well, and Archer is beaten during questioning.
The suspicions of Keval's commander prove to be justified. After a fight in the catacombs, the humans uncover the surveillance station beneath the monastery and Archer lets the Andorians leave with the proof.
