Freya (portrayed by Laura Donnelly) was a Druid girl who lived in a village near mountains and a lake. After killing the son of a sorceress out of self-defense, Freya was cursed to become a magical monster that resembled a large panther with bat-like wings on the stroke of midnight, with an insatiable desire to kill that she would be unable to control. Under unspecified circumstances, Freya was captured by the bounty hunter Halig and taken to Camelot, only to be freed by Merlin. Hiding Freya in the underground catacombs, Merlin brought her food and told her about his magic, the two being drawn together due to Merlin's relief at having someone who understood him and Freya's gratitude at meeting someone who did not consider her a monster. Unfortunately, her curse resulted in the deaths of at least four people when she transformed during her two nights in Camelot, prompting an increased hunt for her. Merlin and Freya began to fall in love. Although Merlin had planned to leave Camelot with her, Freya attempted to escape on her own, not wanting Merlin to abandon his life for her, only to be cornered by Halig and Arthur's knights just before her transformation. Although she killed Halig, Arthur was able to mortally wound her beast form, the creature only escaping after Merlin caused a distraction by causing a gargoyle statue to fall over, creating a path for her to escape the knights and retreat down to the catacombs. Although beast-Freya appeared calmer around Merlin, calming down simply from the sight of him even when surrounded by the knights, the wound Freya had sustained proved to be fatal, staying alive only long enough for Merlin to take her to the nearby lake. As she died, she thanked Merlin for making her feel loved again, promising to repay his kindness one day. Merlin put her body on a boat and gave her a Viking-like funeral, clearly mourning his inability to save her.
It was revealed in Merlin: Secrets and Magic that Freya will somehow return and aid Merlin on his adventures. This came true in The Coming of Arthur, when a vision of Freya appeared to Merlin in the water that the Fisher King had given Merlin, informing him that the sword Excalibur was hidden in the Lake of Avalon and that she would give it to him. Excalibur was the only weapon that could kill the immortal army of Morgana and Morgause's doing.
