Year 12: The survivors get invaded by a horde of Thrumbo, in numbers believed to be what's left of their entire species.

Even with the battleship and defenses, the Thrumbo overrun them and they are forced to flee the settlement.

Only about 3,000 survived the swarm. The settlement, along with the defenses, fell into disrepair.
