A Xindi-Arboreal who runs a kemocite refinery without knowing it is supplying the weapon meant to destroy Earth.
Gralik Durr is a Xindi-Arboreal who mines and refines kemocite on contract for Degra. In The Shipment, Archer, Reed and Major Hayes infiltrate his settlement and confront him at home, and Archer reveals that the kemocite is a component of the weapon being built to destroy Earth.
Gralik says he never asked what it was for and that Degra told him it was for research. Archer chooses not to destroy the civilian facility, and Gralik's account of Xindi history and politics gives the crew a fuller picture of the species they are hunting.
