Orleon was a rainy planet in the Mid Rim. The rain was torrential and never stopped, leaving the planet covered in mud. In 19.9 BBY, the freighter Spinner was believed to have contracted stone mites on Orleon before crashing at Westport, Coruscant. As he believed this indicated a Confederacy of Independent Systems facility on the planet, SBI Director Armand Isard ordered the planet infected with weapons-adapted stone mites. They ate through the planet's crust, and Orleon's entire population of 800 million were forced to evacuate.
