And yes, the Pope is a Dandolo but a different one from the Venetian dynasty from the fourth crusade and sack of Constantinople. Honorius III died a little later (about fifteen months) than historically and instead of Gregory IX, who excommunicated Frederick II and threatened to depose the bedridden Emperor we have an accidental namesake of Enrico Dandolo. There will actually be a Gregory IX in less than three years but not the same person.
