Izembaro is the manager of a Braavosi troupe of actors, in which he also acts.
Izembaro is a larger-than-life actor who specializes in portraying drunken aristocrats. He is a huge presence on stage and rather nasty to his company when off-stage.
In The Bloody Hand, a farcical account of the events preceding the War of the Five Kings, Izembaro plays King Robert Baratheon. After the performance, he chides Bianca for wanting her role expanded and for not "ringing true" on stage.
In the second act of the play, Izembaro plays Lord Tywin Lannister. When he retires backstage, he says that he found the day's crowd particularly bad, and complains that they were "worse than animals". Lady Crane tries to suggest a change to the script, so he mocks her for trying to rise above her station, and claims she has no right to an opinion because he has been acting all his life. He watches in bemused shock as Arya Stark spills Crane's drink and accuses Bianca of wanting Crane dead.
Izembaro later loses both Bianca, whose face has been mutilated by a vengeful Crane, and Lady Crane herself who has been killed by the Waif.
The playwright of a traveling company who wrote and directs "The Bloody Hand", a theatrical production of The War of Five Kings currently running in Braavos. Izembaro also stars as Robert Baratheon and Tywin Lannister.
