Irrth was a planet in the Outer Rim. It was most notable for being the location of the Mary-Sue Jedi Academy. Irrth was mostly ignored in galactic affairs and had little contact with other planets, so not much was known about the planet. Its geography was varied, with climates from tropical heat near the equator to disagreeable cold at the poles. Everything from rain forests to volcanic wastelands to deserts to grassland could be found on Irrth, making it an excellent location for a training school.
