The description of the thought bomb in Drew's Darth Bane: Path of Destruction:
Vitiate feeds on the conflicts of The Old Republic - gathering enough power and moves to Ziost
After he fed on the conflicts, he possessed the people on Ziost:
Koepcz describing the thought bomb:
From my understanding what Vitiate does on Ziost is similar to a thought bomb. He mind-controls those individuals and makes them cause slaughters which in turn release Dark Side energies in the corporeal reality. Vitiate draws those Dark Side energies towards himself and converts them into a Dark Side blast - and essentially he turns himself into a thought bomb. And he does not really drain anything, the Dark Side blast does that for him. Given that Vitiate is "at the epicenter of the detonation", everything that is drained - naturally - it is directed at him.
Bellow you have an image with visual depiction of the thought bomb and Vitiate's Ziost Cataclysm
