Marathon

The Marathon came under surprise attack from the Pfhor, a race of alien slavers who had acquired their technology from the remnants of the ancient Jjaro civilization, struck without warning. They vaporized the colony's spaceport with orbital bombardment, then began their assault on the Marathon itself. Leela was damaged. Tycho was destroyed. Durandal appeared to be critically compromised.

The tenth cyborg, returning to the Marathon from the colony on a shuttle, arrived at Airlock 54 at 0842. This unnamed Security Officer began working with Leela to repel the Pfhor invasion.

What followed was a desperate fight through the corridors of the Marathon, a battle told entirely through computer terminals: green-text briefings from Leela, taunting messages from Durandal, and desperate status reports as the situation deteriorated.
