Porst was a mature human male character. He operated the depot located in Tikaroo, which was a city situated on the planet of Devaron. Not long after the events of the Battle of Yavin, Luke made a landing close to the settlement with his BTL-A4 Y-wing assault starfighter/bomber. Luke then made his way to the depot with the intention of resting and locating a guide to take him to the Temple of Eedit. Porst believed it was a place of wickedness, inhabited by a demon, and suggested staying at the depot was the wiser choice. Ultimately, Luke encountered Sarco Plank, who then served as his guide to the Temple.
