*picks jaw up off floor* Oohhhh man this is NOT what I was expecting at all O.O (in the best way possible ofc!) Oh wow, okay this is big...these guys are bad news. 

I second that motion, help is definitely needed from Cheriss AND ghost dad XD 
Hmmm, suggestions in so far as how this goes:
-so I assume the Five are going to appear and all kinds of crazy is going to go down XD Illesia, I figure, escapes in the chaos and flees to the ice moon (something Prime, wasn't it? ouo)
-Our dynamic duo have to engage the Five/the other Xiis of course in order to attempt to fight their way out, Cheriss senses that they're in trouble and appears to their aid with ghost dad in tow (because no way would he sit out of this and watch them hurt his little Ari XD)?
-big fight? I'd assume that although powerful and although Illesia has been "feeding" them with the Force users on Dromund Kaas the Five would still be 'weak' enough for our duo, the dogs, ghost dad and Cheriss to overpower between them? 
-We could certainly kill them here potentially, it'd be a good and epic ending for the DK arc, depends on whether you had anything else big planned for them I guess? XD
