A Xindi held in a mining camp, the first Xindi Archer meets in the Delphic Expanse.
Kessick is a Xindi held at a mining facility in the Delphic Expanse. In The Xindi, Archer and Tucker go undercover at the mine to question him, the first lead Enterprise has found in its search for the species behind the attack on Earth. The foreman agrees to trade Kessick for platinum, but the deal goes wrong.
Kessick helps Archer and Tucker escape, and shares what he knows of the Xindi before dying of his wounds. His information sets the direction of the search.
