This is an idea I had some time ago, so i thought i'd get some opinions on it.
I think that they should add the Planet Lehon as a new world. Lehon is the homeworld of the Rakata, so there is incredible story potential there. It would most likely be another high level planet, likely from 55+.
I have a bit of an idea of what the story could be.
An imperial scout ship accidentaly re-discovers the planet Lehon in the unkown regions. Seeing an opportunity to exploit the ancient technology of the Rakata for their own use, the Empires Dark Council sends a force to ally with the locals and gain access to what remains of their advanced technology, and salvage what remains of the star forge. The Republic however, discovers this plot and sends their own fleet to the planet to ensure the Empire is never again able to recreate a weapon as horrible as the star forge.
So theres my idea, any comments are encouraged.
