In this episode we head back to 1204 and pick up the narrative of the Byzantine Empire after the sack of Constantinople by the Fourth Crusade. The sack of Constantinople leads to a crusader/Venetian coalition in charge of what had once been the greatest Christian city in the world. True to their style, the crusaders waste no time in fighting amongst themselves. Meanwhile, in Nicaea and Epiros, two rival successor states to the Byzantines work to restore all that remains.
