Alinor

Alinor is an enemy of Camelot. When Merlin was captured by mercenaries that ambushed the Knights of the Round Table in the Valley of the Fallen Kings, Agravaine suggested to Arthur that they were sent by "that snake Alinor", though Arthur didn't think so as their route was kept top secret. Unknown to Arthur, the one who sent the mercenaries was actually Agravaine himself. (A Servant of Two Masters)
