Bellatrix

Ballatrix was a double star system located in the Orion constellation, roughly 324 light years away from Earth. It was composed of a white dwarf and a companion star. Material had been siphoned off the companion star into the white dwarf until it went nova in 1644. The Sentience fed on the energy of the nova. (NA: Nightshade)
