Xirrinda was the home planet of the Ulla people. The planet was covered in forests, mountains and caves. This was where the Rain of Terror was created. After raging across many planets, the creatures returned home to devour Xirrinda as well.

The planet was turned into a major tourist attraction for scientists and schools. There was both Ortagon City and a hotel within a forest of wildlife to stay at. (PROSE: Rain Of Terror)
