Just noticed I hadn't even reacted to this great update, shame on me. This was a twist worthy of an Emperor, setting up a perfect scheme with the Great Khan himself in order to rid themselves of a mutual threat.
Guess the story will enter a new chapter now, with the Thomasine branch humbled and weakened and Arghun and Altani dead. Will it be time for some old fashioned uprising? The Italian communes and citystates must be biding their time, the Spaniards are still enraged (please avenge Barcelona), the Egyptians have been too quiet for too long. Thats not counting the Western powers and Catholic church too.
What was the fate of Albrecht by the way? Did he just fade out of history like that after exile?
