The Pii system was an Outer Rim Territories star system in Arkanis sector near the Mid Rim border. It centered around the star Pii and contained seven orbiting planets and two separate asteroid belts. The system was sold to a Corulag entrepreneur when preliminary mining expeditions were fruitless, but eventually developed a profitable industry centered around the logging and export of luxury greel wood from the planets Pii III and Pii IV.
