UESC Marathon
Humanity's first and only interstellar colony ship. Three kilometres long. Home to 10,000 colonists.

The UESC Marathon is humanity's first and only interstellar colony ship — a vessel three kilometres from stem to stern, carrying over ten thousand colonists and managed by three artificial intelligences. Launched from the Sol system, the Marathon has been in stable orbit around Tau Ceti IV for eleven years when the Pfhor attack. The ship becomes a battlefield in the first game and is partially abandoned as Durandal flees to Lh'owon.
