Sarahwiee was the third world orbiting the white dwarf Bseto in the Mid Rim. A frozen planet, its local day was 28 standard hours long, and its year was 389 local days. The planet was discovered shortly after the declaration of the New Order. Emperor Palpatine kept its location a secret.
The planet was the site of a research base. After the Battle of Bilbringi in 9 ABY, Luke Skywalker and Alexandra Winger led agents of the New Republic to the base on an infiltration mission. The mission, part of a contracted supply run, allowed the New Republic operatives to free captive scientists, including Carl Barzon.
