Ithorians are natives of the planet Ithor, a lush world with sprawling rain forests. The Ithorians worship Mother Jungle and long ago vowed never to desecrate their planet. Once they discovered repulsorlift technology, the Ithorians built expansive "herd cities" floating in the skies above their home world. The species migrated to these platforms, ensuring that Ithor would remain pristine forever. However, the Yuuzhan Vong destroyed their planet when the second in command released a plague that turned everything into a black sludge.
