Phatrong was a terrestrial planet located in the galaxy's Outer Rim Territories. It was covered in oceans divided by thin and mountainous continents, and was home to the Kyuzo species, who evolved several adaptations to the world's heavy gravity. Phatrong was governed by a loose Kyuzo confederation that elected its senators in the Senate of the Galactic Republic and later its successor, the Imperial Senate; this lasted until the Galactic Empire took direct control over the planet after the Senate's dissolution. The Kyuzo bounty hunter Embo hailed from this world.
