- "According to ancient warnings carved into the walls of Belsavis prison, the Esh-kha were once one of the most feared species in the galaxy. In the distant past, they rose from their isolated homeworld and cut a swath of destruction across countless systems. Entire species were hunted to extinction. This marauding was only stopped when the Rakata “Infinite Empire,” which had lost dozens of its slave worlds to the Esh-kha, mustered its titanic military against them. The Esh-kha were imprisoned in stasis beneath the surface of Belsavis–conscious, but immobile–and left in darkness for thousands of years. Since the security of Belsavis has begun breaking down, the Esh-kha have resumed their campaign of ruthless expansion and zealous combat. They appear devoted to releasing all of their kin on the planet, and spreading as much chaos as possible in the ancient prison. With every hour that passes, they recover more technology and strange weapons; it is only a matter of time before they take to the stars again."
