Windblown

The Windblown is a sellsword company active in Essos. Their name is "the Windblown" because they say the wind blows them around from one city to the next in Essos, looking for employers who will contract them to fight.

In the books
In the A Song of Ice and Fire novels, the Windblown were founded about thirty years ago by an exiled prince from Pentos, known only as the Tattered Prince (due to his habit of taking strips of cloth from the surcoats of men he has killed in personal combat, then adding them to his motley cloak). He is an elegant and dignified old man who is nonetheless ruthless to deserters. When he was 23 years old, the magisters selected him as the new Prince of Pentos after beheading the last prince for failure. Rather than accept the title (a dangerous position as a glorified scapegoat), he ran to the Disputed Lands to become a sellsword, and never returned. Over time he established his own sellsword company.

Because the Windblown include members from all over the world, the only common language they can use is High Valyrian, which the Tattered Prince shouts out commands to his men in.
