Viserys I Targaryen Image via HBO One of the kings depicted on House of the Dragon, Viserys bequeathed the throne to his daughter Rhaenyra, and then had several sons during his second marriage. The five kings in question were Robb Stark, Joffrey Baratheon, Stannis Baratheon, Renly Baratheon, and Balon Greyjoy. Each king had their own level of success within the war and each man had his own set of strengths that made them a contender as well as weaknesses that led to their downfall. Renly's Strength: Likability From the roughly twenty thousand northmen who marched south with Robb Stark at the start of the War of the Five Kings, only one in five returns north, most of them men from House Bolton. According to Theon Greyjoy , Roose later has six thousand men or more at Winterfell . TzR2UKP.
