Centauri

Centauri was a planet that was destroyed by the Oroborus at some point prior to 2050. It turned the planet into a black hole by siphoning its future. (TV: Oroborus)

The destruction of Centauri may have been related to the Centaurian Catastrophe. (TV: Aeolian)

Behind the scenes

 * Due to its name, it is likely that Centauri is located in the Centaurus constellation. The fact that Proxima Centauri is the neighbouring star to Sol, and that the Oroborus targeted Earth, supports this.
