The Aedirn Special Forces were a group created by king Demawend of Aedirn to fight the Scoia'tael. Their weapons of choice were black, gold and red bows, but they carried other weapons as well. They were divided into several units. Rayla's unit was deployed to Vengerberg during the Nilfgaardian invasion. They were surprised to find elves rather than Nilgaardians there.
