Geth Holdouts

The Geth Holdouts was a group of remaining Geth outposts spread across the galaxy after the Expansion War which was wiped in completely in 2185, which was thought to be the final dead of the Geth. Instead, Geth Prime came back with an army from an unknown system, presumed to be beyond Omega 4 Relay. It was formed by two remaining members of the Geth, Geth Prime and Legion in 2182. The Geth holdouts gained string of minor victories before the Systems Alliance-Collectors War started.
