I don't ever remember Aria using that before, but man, I imagine that we might see that in battle sometime? 

Anyhow, so with Meetra dead and Vitiate officially introduced, I'm thinking:
-Revan is going to be worried about Vitiate trying to find the Heralds, so he might be proactive in terms of disabling any kind of threat to his order. I mean, the Heralds have managed to remain a secret so far, but I imagine that Vitiate will be able to find them sooner than later. Better to divert his attention somewhere else? 
-Vitiate managed to sustain himself enough to maintain a presence in Arcann, but I imagine that his goal from here on would be to find a more permanent host. Wouldn't that be Revan? 
-I'm conflicted as to what Vitiate's ultimate goal would be. Is it complete annihilation of organic life like Nihilus? Or would it be the consolidation of power within himself by disconnecting any and every person with a connection to the Force? I would think more the latter because he did choose to rule over the Eternal Empire, which has human subjects who are doing quite well thanks to his rule. 
-In terms of next steps, Revan would probably want the Heralds to somehow scatter, right? So that Vitiate won't find them all in one place? Or would he want them all to stay together? In any case, they would have to find ways to weaken Vitiate and rob him of his power, right? If so, what ways would they consider? A thought just came to mind about the True Sith potentially crafting sabers that could drain one's connection to the Force and hiding them in remote corners of the galaxy as a safeguard from any one Force user completely shifting the balance of power to him or her. What do you think?
