The northern third, with capital at Oreoi, was divided between Ravano's nephews, Merino I and Rizzardo; the central third, with the island's capital, Chalkis, was divided between his widow, Isabella, and his daughter, Bertha; and the southern third, with capital at Karystos, was divided between Giberto's heirs, Guglielmo I and Alberto.
