For all you Bane haters
When Darth Bane's body is killed, he tries to take Zannah's via essence transfer, but fails in the attempt (Drew confirms this), and so his spirit is cast into chaos.
Here is what Andeddu's Holocron had to say about essence transfer:
"Choose your new vessel carefully. If you select a living being, be warned that their own spirit will fight you as you try to possess their body. If their will is strong, you will fail and your consciousness will be cast into the void, doomed to an eternity of suffering and torment."
