Kuthar is a hostile world located within the Krogan DMZ. It went unnoticed for centuries until the Tuchanka State Union arrived sometime during 2251. The krogan quickly colonized Kuthar, at first only to gain more ground and resources for their empire. Kuthar was later transformed into a training world, mostly for vorcha soldiers of the Tuchanka State Union. The incredibly hostile climate varieties, dangerous wildlife, and resource shortages forced the vorcha to adapt and become extremely powerful warriors or die.
