The Second Sons
The Second Sons are a sellsword or mercenary company with a long history. Before the Battle of the Three Thousand, the Second Sons fled Qohor and left the city’s Unsullied to defend it from an approaching Dothraki khalasar. Prince Oberyn Martell rode with the company for a time. The company numbers about five hundred soldiers, including lancers and mounted bowmen. They are led by Mero, a large Braavosi called the Titan’s Bastard.
During Daenerys’s campaign in Slaver’s Bay, Yunkai hired the Second Sons to defend it against Daenerys’s army of Unsullied. Daenerys gained an easy victory over the Second Sons by giving them a gift of wine and attacking during the night while they were inebriated. Mero escaped and mixed in with Daenerys’s followers. He later attempted to kill her, but was thwarted by Ser Barristan Selmy. The remaining members of the company chose to ally with Daenerys, and elected Brown Ben Plumm as their new captain.
