A forested Xindi colony world with a facility that refines kemocite for the weapon being built to destroy Earth, managed by the Xindi-Arboreal Gralik Durr, who knows nothing of its purpose.
The colony is the setting of The Shipment. Following the coordinates supplied by Tarquin, Enterprise finds a complex where Xindi-Arboreals process kemocite, a volatile compound that turns out to match traces in the wreckage of the probe that attacked Earth.
Archer, Reed and Major Hayes infiltrate the plant and confront its director, Gralik Durr, in his home. Gralik is appalled to learn that his kemocite is going into a weapon and that seven million people have already died, and he tells Archer something of Xindi history, including the destruction of the Xindi homeworld and the extinction of the Avians.
Rather than blow up the facility, Archer accepts Gralik's help. A canister in the shipment collected by Degra is tagged so that Enterprise can follow it, and Gralik quietly spoils the rest.
