Prince Rhaevo was the Prince of Pentos at the end of the War of the Brothers. He led the Pentoshi host for the last two battles.
During most of the War of the Brothers, the Prince was Good Prince Illyrio. He had been elected several years before and had cleaned up many of the city's woes. According to legend, when the Thousand Banners moved for Myr he willingly gave himself up for sacrifice so that Rhaevo, who was a man of war could take his place.
