A Gatherer outpost was a small encampment of Gatherers, the nomadic marauders who hailed from the planet Acamar III. The first of these outposts was established in 2266. Since then, these outposts have moved location, from star system to star system, making them difficult for Acamarians and Starfleet alike to find them. In 2366, a Gatherer outpost was discovered on the planet Gamma Hromi II by the Federation starship USS Enterprise-D.

In the early 24th century, Volnoth, when reaching the Age of Majority, fled his homeworld for the Gatherer outposts

In 2366, the Gatherer outposts were mentioned in the birth record of Volnoth, which was accessible to the crew of the Enterprise-D via the Acamarian planetary database. (TNG: "The Vengeance Factor", okudagram)
