Kieran Redsteel

Kieran Redsteel was the Captain of a breakaway faction of the Second Sons. Some time following the death of Daenerys Targaryen during the Great War, he became a leading voice of discontent within the Second Sons as to continuing their roles as peacekeepers within the Kingdom of the Bay of Dragons, eventually culminating in him leading around half of the Second Sons' numbers to breakaway from the authority of Daario Naharis and return to contract work, with Keiran Redsteel being elected Captain. In 310 AC, Kieran Redsteel's Second Sons were hired by Asaro Trellos to defend Myr from the invading Westerosi armies. During the ensuing Battle of Myr, Keiran's forces were decimated and his breakaway faction was effectively dissolved in the battle's aftermath. Kieran himself survived the battle and went on to pursue solo mercenary work.
