The Rift

The Rift was a phenomenon caused by Sith magic. My manipulating gravity, a sorcerer could cause a small star, planet or other heavenly body to compress and create a black hole. The holes' dimensions varied in size depending on the caster's power and skill with this spell. The black hole would then act as if it was created through natural means, thus adjacent planets would orbit it or even be consumed by it due to its extreme gravitational pull.
