"A caster of some sort" - there's your surprise that can ruin the day even more. Hatomancer + Surprise Caster... what can they do? Combine that with new leadership (Tremennis) and a pretty powerful Royal ally (Jillian) and Jack probably being out of commission for at least a turn, and the capital can yet put up a fight.
Speaking of which, Jillian is indeed in Jetstone! Let the fun begin.
Ansom disapproves of murdering his own brother. He then gets to see exactly how much decryption can do to someone's mind. Next he gets to encounter Jillian, whom he used to love.
Suddenly, I think that Ansom turning and us finding out that decrypted aren't perfectly loyal... a much greater possibility.
I wonder what interaction Wanda will have with Jillian. Her expression was certainly a sight to see. (Though I'd much rather have Wanda herself be back to 'a sight to see', rather than 'a horrid monstrosity to avoid looking at'.
