De Firiac probably wouldn’t leave a rebellion led by Jack Sparrow, but also wouldn’t romance the leader. Honor is too important.
De Firiac doesn’t know the de Tomans, including Abelard.
Kala/Kalt may find the idea of a Grand Moot or pirate confederation appealing-- as long as it can’t be dominated or taken over by the nobility, or hamper the vengeance of former helots against their former masters.
You don’t really mean “self-controlled” here–none of K’s attacks are done on blind impulse–but MC-controlled. And the answer there is definitely no.
K could well be the “bad rebel” to your “good rebel,” but it wouldn’t be an act, and they wouldn’t stop just because it was hurting your efforts to make some noble alliances.
Might be!
Definitely. 
But to influence the Cabelite leadership choice you’d really need yeoman clout, not just homelander aristo clout.
The Abhumans don’t feel they have anything to learn from the Inert on this topic.
Breden knows what they want, and arrogant ain’t it.
A few years.
Thanks for all the kind and insightful commentary! I’m so glad you enjoyed the game. You’re not wrong about the Ch1 rescuer; it’s an unlikely escape. But having established with the framing story that you become at least a minor legend as a rebel, I wanted there to be a way forward out of the Ch1 fail options too–and an early connection to more than one of the major factions. I figure if I’m asking my readers to accept a lucky escape anywhere, the origin story is the place for it. There are plenty of nasty brutish endings to be had later on.
