Galaxy map showing relative location of Tau Ceti
Tau Ceti is a star system in the Cetus constellation. It is the location of the colony that was attacked by the Pfhor in 2794.
The Tau Ceti colony was where Robert Blake once worked as a technician. It is also where the nine Mjolnir Mark IV Cyborgs revealed themselves hiding among the human colonists, and helped to single-handedly turn back the assault. However, three months after the defeat of the initial assault, the Pfhor returned in force and destroyed the entire colony and the UESC Marathon.
