Figuring out my own exit cues for classes that won't be the Outlander is kind of fun.
My sorcerer is already preparing to go to ground. He's scouring all sources of knowledge he can find for what Sith rituals or powers might be able to put him on equal footing with Vitiate or at least render him immortal without the cost Vitiate incurred. Ultimately he might decide to do what Vitiate himself did during the Great Hyperspace War and just go into hiding, ready to rise again when the time is right.
My agent is basically doing the non-Force version of the above, only she's actually trying to save the Empire and its people from behind the scenes. Sith are not generally not included in that reasoning so it's a fine line indeed. If **** hits the fan, she'll calculate and gather intelligence on the best way to respond before revealing herself.
My warrior will have to be captured or killed.
My BH just hunts things. So he can be away on a long job. Or, since he's a Chiss there might be business for him to take care of back in the Ascendancy (even though he's exiled).
I've already thought of a capture for my Knight prior to the Fallen Empire hitting that's dependent on his backstory as well. The consular could be away searching for him. Smuggler and Trooper might get stuck with it, the former just because it's a smuggler in carbonite. His droid eyes won't be affected I don't think.
All of this subject to change once we find out what the story is of course.
