SWTOR Codex wrote:For most galactic travelers, the planet Athiss barely warrants a second glance on the scanner. It appears to be nothing more than a small world off the Descri Wris hyperlane, with little of interest besides a scattering of unexplored ruins. But the Jedi Archives tell a grim story. The Jedi Master Chamma visited Athiss early in his career and clashed with a dark side entity there. The duel, and the oppressive feeling of evil on Athiss’s surface, drove Chamma close to the dark side of the Force. Shaken by the experience, he went into a self-imposed exile; it was almost a century before he came to terms with what he had seen and felt on Athiss, and was able to return to the order. The many ruins on Athiss have never been properly studied. They resemble the architecture of the ancient Sith Empire, but their purpose is mysterious. A few records of Athiss survive in the libraries of the Citadel, but contemporary Sith scholars are forbidden from studying them, on the personal order of the Emperor.

Luke could sense the dark side here more strongly than anywhere else he could recall. And even he found his stomach clenching and his skin erupting in goose-flesh; he, who had looked into the face of the dark side and defeated it more times than he could recall. The evil was not merely ancient. 

it’s the whole miasma of the place. I’ve never seen anything like it, and that makes me very wary of it.”

Toward a city more full of concentrated dark-side energy, of hate, and anger, and fear, and violence, than anything Luke Skywalker had known before.

This is a quietly seismic revelation if taken at face value, since it means Upekzar is more potent than Abeloth, Sidious, Exar Kun, Byss, etc.

Release date is 2016. I wouldn't use anything that isn't expressly Legends (even the it's a bit vague since the book series seems to treat Legends as actual in-universe tales in Canon)
