Trellium-D mining complex

Slave-worked mine in the Delphic Expanse

A brutal mining colony just inside the Delphic Expanse where Archer finds the first Xindi anyone on Enterprise has met, and where the ship's MACOs see action for the first time.

The mining complex is the main setting of The Xindi, the first episode of the third season. Six weeks into the Expanse with nothing to show for it, Archer follows a freighter captain's tip that a Xindi works in the mine.
The foreman lets Archer and Tucker see the man, a Xindi-Primate named Kessick who has had a finger cut off as proof of identity, in return for a payment of liquid platinum. The foreman's real plan is to keep Enterprise's crew as new labourers. Archer, Tucker and Kessick try to get out through the plasma ducts, and Major Hayes's MACOs storm the complex to pull them out.
Kessick is fatally wounded. Before he dies aboard Enterprise he gives up the coordinates of the Xindi homeworld, and the crew learn that there is more than one Xindi species.
