In the book, each era has its own emperor. The show invents the Genetic Dynasty: clones of Cleon I who rule together, one young, one on the throne and one old.

source ↗ - ChangeThe Mule, undisguised
In the book, the Mule hides until the end: he was the clown Magnifico all along. In S3, the Mule shows up in the very first episode as a feared pirate played by Pilou Asbæk, and Magnifico is played by a different actor, Tómas Lemarquis.
source ↗ - ChangeRiose falls a different way
In the book, Bel Riose is brought down by Emperor Cleon II himself, who has the general arrested out of fear of his power. In S2, Riose works for Brother Day and his fate runs through Hober Mallow.

source ↗ - ChangePreem Palver, no secret
