Lehon

Lehon was the homeworld of the weird-ass Rakata. They ruled a huge galactic empire for thousand of years, then got old and bored and retired to beachfront property. Darth Revan visited there, got the locals on his side by rabble-rousing, reactivated the Star Forge, and almost overthrew the Galactic Republic. Darth Bane also visited Lehon, to study from Revan's holocron and also get a nice tan.
