Alinor

Alinor was a supposed 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 believe this as the route that the Knights of Camelot and Merlin had been taking was kept top secret. Unknown to Arthur, the mercenaries were actually sent by Agravaine and Morgana (A Servant of Two Masters).

Personality
Having been characterised as "snake", Alinor may possess a cunning and mischievous personality. However, he was never actually seen. It is uncertain if he actually is an enemy of Camelot. It is possible that he is in fact an ally but Agravaine wanted to mislead Arthur once again, perhaps with the intention of having Arthur make a strong and powerful enemy.

Trivia

 * Alinor is apparently, the leader of the mercenaries that patrol the Valley of the Fallen Kings.
