Phelarion was a planet located in the Seswenna sector, in the Outer Rim Territories. In was the homeworld of the wealthy Motti family, which included figures prominent in the Galactic Empire such as Lady Thalassa Tarkin, wife of Grand Moff Wilhuff Tarkin, and Conan Antonio Motti, Admiral of the Imperial Navy. The Motti family were wealthy citizens in the megonite moss mining business, established in the centuries prior to 60 BBY, using slave labor.
Lady Tarkin erected a solid black obelisk on Phelarion in tribute to Tarkin and named the main starport Port Tarkin. She ran the mining operations for the Empire, but they were sabotaged by Leia Organa, who crashed on the planet after her ship was shot down by a TIE fighter.
