Power Over Life and Death

The Power of Life and Death is a form of magic which can be used to revive people who are dying as long as a life is given. This power can also be used to give a life to a baby if a woman is unable to give birth as shown when Arthur Pendragon was born as his mother Ygraine was incable of giving birth. This form of magic is very powerful and can only be achieved by powerful and experienced sorcerers. Only two known people have mastered this power - Nimueh and Merlin.
