In the Ruusan system, circling the star known as Hoth's Brand, was the fourth planet, a desolate world called Turpimir. This planet was situated in the Teraab sector within the Mid Rim.
The Jedi Knight with the name Turpimir is the namesake for the planet.
When Jerec was on Ruusan seeking the Valley of the Jedi, and invading the planet, the majority of the ships that made up his Vengeance Battle Group were still positioned near this fourth planet in the star system.
