I haven't actually gone over the ritual and what it does.

It is called Deformis resuscitatio or The hideous revival. It is said to bring back the dead to life. Although there is a side effect. You will need a peice of animal or your body and then the person can come back Although the side effects are bad. The person will remember there past lives at the age of ten and will suffer frequent nightmares from it. They will have a Feral side which will make them uncontrollable and cruel or more animal like they will act like wild creatures. They must eat human meat once a month or they will suffer extreme nightmares or visions. They can die multiple times and be reborn but if the person can't have children the soul will find a random body and be born from that, either mualing or killing the person carrying them. They remember all there past lives and every single detail. This ritual can't be reversed nor fixed. The person a hideous monster
