Corion was a small world where the Entari warrior Irik’Tai Abitaar made his historic last stand against the Pulse, sometime in the thirty-first cycle. A large portion of its surface was covered by dense forest, and it was constantly bathed in darkness. Notable was a bright red star which glowed bright above the planet. In the year 43c19, the Forty-Ninth Council launched an all-out attack on the planet in order to destroy an unidentified rebel cell. This attack resulted in the destruction of much of the forest, wildlife, as well as damages and casualities to many peaceful species, such as the Taurans.
