I think we could work the Exile being somehow alive into it as well if we wanted, its not unplausible if Revan is still alive too after all right? :3 and it might be another cool dynamic to play around with for an Act too :)
Carth would have been awesome, had he been Force senstive or otherwise long-lived, but alas! XD We [i]might[/i] be able to squish Atton in along with Exile though if that strikes your fancy? XD 

Wouldn't be Manus if he wasn't slippery, after all! :P Sounds good, I shall get working on something this evening!
