Every year on the same date, a silent figure appears on the abandoned Outer Ring of Station Zero and walks its length.

No one knows who—or what—it is.

Security recordings fail. Witnesses disappear.

Now several factions want the truth.

This is the eleventh year.

Year Eleven is a sandbox investigation and survival adventure for Mothership 1E, built around faction play, station exploration, and a mysterious alien presence stalking the station. It features a threat designed to be utilised well beyond the scope of this adventure; integrate it into your home campaign to challenge your crew with something that preys on sentient life.
