The Void (Sith magic)

This was a very powerful and blasphemous Sith magic ritual performed by the sith lord Vitiate with the help of other sith lords in order to gain immortality. By doing so he essentially "ate" all the lifeforms on his homeworld Nathema along with the force itself. He would replicate this technique on a lesser scale centuries later, in order to grant his newest disciple Lord Scourge (Sith) immortality as well.
