"The Movers are Progenitor AI constructs. They know no age, no despair. All this time they have tendered the derelicts of their masters." — Narrator in Homeworld 2
The Progenitor Movers were AI-controlled corvettes created to transport and guard Progenitor artifacts. Each Mover contained memory banks with interfaces compatible with Hiigaran technology. Movers were the first Progenitor ships met by the Hiigarans during the Homeworld 2 era, defending wreckage in the Karos Graveyard.[[Homeworld Shipyards|]]
After suffering considerable losses at the hands of the movers, the Hiigarans managed to capture a damaged mover in the Karos Graveyard and developed weapon modifications to defeat them more easily. They also created a Mover Construction Facility in the Mothership to produce their own movers. They proved ineffective in combat against the Vaygr, however, as the Vaygr had already developed the same anti-mover weapon modifications.
Movers were the only ships able to capture a Progenitor Dreadnaught, so the Vaygr must have at one point used their own Movers to seize their Dreadnaught. It is also known that Progenitor Movers were shielded from radiation, which proved useful for the Hiigarans when they were trapped by radioactive debris in the Karos Graveyard.
In the Homeworld 2 demo it was possible to build Progenitor Movers in the multiplayer game, and to perform the Anti-Mover research. This revealed one of the campaign opponents long before final game was released.
The Mover schematics shown before the mission containing the Dreadnaught berth are sightly different from the in-game movers, which suggests what Movers looked like in the early development stage.
