Merlin season 4

Full of anger and hatred Morgana seeks revenge for everything that happened to Morgause. Her sister gives her the last present and brings the voluntary sacrifice before dying. Although Morgause’s death is irreversible the thing she did provoked many consequences going too far. The deadly Dorocha spirits are unleashed and they start their terror in Camelot which causes the deaths of thousands among the people. To seal the Dorocha again another sacrifice should be done and there will be a person who is ready to implement it. To win in her plans Morgana has to find a new ally and she steps into the union with Agravaine, who is Arthur’s uncle. This will bring more deaths, but even the upcoming fail won’t stop her from doing more and more awful things.
