Resurrection is a branch of magic in the Daughter universe that allows one to create new bodies for souls that can still inhibit them. Complex and mysterious, it is only said that Brimstone, Madrigal, and Karou can perform resurrection, however it seems that Zuzana Novakova might be able to perform this type of magic, as well, but at a smaller rate.
Resurrection is not child's play; a difficult and very precise art, it demands a great deal of skill and attention to detail. It requires teeth in order for it to be performed.
Resurrection, though extraordinary, is not a end-all to death; if a soul if not placed in a thruible and kept secure until a body can be made for it or it can be placed in one, it will not matter if a body is made or kept stable.
