The Forge acts as a massive holding ground for the Reavers, with the Elite Force being shocked by the sheer number being held in stasis - enough to conquer the Galaxy, to be exact. Fought within the Forge as well as during the climatic battle with the Vohrsoth the Reavers are ultimately destroyed en mass when Voyager completely destroys the Forge following the death of the Vohrsoth, limiting the threat the Reavers can pose to the Galaxy and preventing the release of a "Seed" that would of helped spawn a second Forge, full of similar beings.
