Deer

Deers are an animal hunted by Humans.

History
Morgana enchanted Guinevere to appear as a deer so she would be killed by Arthur, as he was leading a hunting patrol at the time. However, when Merlin saw the deer, he realised that it was Gwen. Arthur tried to shoot it but Merlin made him missed, but the deer was shot by Princess Mithian. Sometime later, Merlin took the injured Gwen and healed her wounds. (The Hunter's Heart)
