Dark Corners of the Galaxy
Ulyoath is a planet in the outer rim which was lost after the fall of the Empire. After being rediscovered by NRAST it was renamed Tanavis prime. NRAST left it unexplored,until recently, for many years due to initial scans determining it to be too dangerous without a properly equipped ship.
During the Empire Ulyoath was used to keep political prisoners as well as Force users far from the public eye. Files recovered by Nerrin Redd of NRAST seem to indicate Palpatine also conducted painful experiments on the Force sensitive prisoners as well as regularly sacrificed them for some unknown Sith ritual. Even while he was away the Emperor’s orders were to regularly torture the prisoners without reason.
Ulyoath has a harsh environment with heavy winds and and icy terrain filled with treacherous mountains and barren plains. The prison area seems to be the only man made structures on the planet. There are no known indigenous life forms known on the planet, but a large number of Metanoks that have been abandoned there seem to thrive.
