Star Forge

This one will be short but sweet.

The Star Forge was a giant automated ship yard used by the Rakata to, of course, construct ships. It was intended to create the ships for the most powerful army of all time. It was constructed by the Rakata Infinite Empire 30,000 years BBY. The Star Forge drew energy from a nearby star and combined it with the power of the Force to create an endless supply of ships, droids, and other materials they used in their conquering of the Galaxy. However, the merciless Rakata used slave labor to construct it and the Star Forge fed off of their evil ways, and became a tool of great Dark Side energy. Eventually the Star Forge began controlling even the Rakata with the power of the Dark Side. This led to the ultimate destruction of the Rakata. The Star Forge was destroyed years later by Darth Revan, the conflicted Jedi turned Sith, as he was somehow able to repress his own Dark Side abilities to keep from being corrupted by the quasi-living structure.
