Born to King Goloris and Lady Vivienne. Morgana did not know much of her mother because she died a few years after she was born due to an illness, which often left her in the care of wet nurses anyway.
She lived with her father in Cornwall, where he ruled over the castle, up until he died by enemies of Camelot and due to a poor decision from King Uther. She was rightfully Princess, now Queen of Cornwall, but was never told it as she was too little to understand back then. As such, King Uther took Morgana in as his King’s Ward and she participated in meetings, balls and such as was requested by him.
She never liked that Uther had such a hatred toward magic, so when Morgana discovered her own magic years later, she was so frightened of it that if her half-sister hadn’t found her, she wasn’t sure if she would have ever gained control of it.
One thing was clear however, Uther needed to be stopped and Morgana sought the crown for herself along with her sisters help. Of course she cared about Arthur, son of Uther Pendragon, but she knew that she needed to break off her connections with him so she ended up stepping away from the castle entirely after a siege had gone wrong.
When Morgana found out who Merlin truly was she felt a deep betrayal. If her sister had not come along, he could have at least helped her and yet he chose not to. Instead he had poisoned her, ruining her friendship and whatever she could have had with him entirely. She sought out vengeance, from Merlin who betrayed her and from Arthur who had her throne.
The battle of Camlann approached and Morgana entrusted Mordred to kill Arthur. He succeeded, but in her guilt, as she watched Merlin carry him away, she wished that things could have been different.
So she waited, lingering but keeping her distance from Merlin whom she knew would never trust her again and she mourned the loss of the King and Mordred, but hoped that one day they would all be brought together again.
King Goloris, leader of Cornwall castle, King, Knight and loyal friend to King Uther, left the castle to Morgana, not that she knows it. Uther kept it under wraps with her and so did everyone else. She only learns of it when she meets her half-sister, Morgause, who is not her father’s daughter, but her mothers. So, using this, Morgana still tries to go after Camelot to take it for her own.
Her magical gifts come from her mothers side of the family.
My Morgana was not killed. She did go power hungry however and seek to have Arthur and essentially Merlin killed but was only successful with Arthur as Mordred was killed in turn.
She waits for Arthur’s return and hopes to earn forgiveness. She realizes that she has lived too long in bitterness and in that too, she eventually will seek out Merlin again too.
