Afterlife

The Afterlife was a tear in the fabric of the Force created by Darth Kullic so that he cvould live even after killed. He survived here, meditating on the Dark Side of the Force and learning what he could from every Sith Lord before and after him until Jedi Master Mosak Jos found a way inside in 78 ABY. The two of them duelled long and hard but eventually Kullic was overcome and was destroyed once and for all.
