It seems the defection of Syrgiannes Palaiologos caused a whole mess of damage to the Empire by kick off the civil war once again.
I was wondering, with Andronikos II and Andronikos III at odds, and Andronikos III the Emperor that lost Anatolia to the Ottomans at the Battle of Pelekanon (partially by my understanding due to inferior numbers) - I assume that the first round would happen anyway. Is it possible that after Syriannes was captured after rebelling, that he could be executed - removing him from the equation and potentially leaving that civil war to only having one round?
IMO That seems the most interesting part - if this can somehow lead to no future rounds so that the Empire can be stronger and expand in Anatolia or at least prevent the expansion by Orhan. A3 certainly seemed interested in this policy, and I think it'd be an interesting PoD.
