Ambria
perhaps best-known as the world which Jedi Master Thon tamed, Ambria was a ringed world in the Stenness System. It was barren and sparse, and was once full of Dark Side energy. Note that, at one point in Tales of the Jedi, Oss Willum says that Thon rid the planet Arkania of the Dark Side, instead of Ambria. When Master Thon arrived there, he pushed back the Dark Side into its source, Lake Natth. He lived there from that point until his death, keeping an eye on the lake and its denizens. The planet became a research location several millennia later, when BioTech Industries set up a campus there. Ambria was orbited by four moons.
