As well all know(most of us) Corpus is a disese that turns the victim into a living zombie, and once reached complete corpus their gone and its only a Zombie left.
But why on earth does then a allmight and powerfull Wizard who are capabel of creating clones of himself using the X-cromosone and implent it as a different gender with other anatomical traits? I mean:
*He is older than the empire
*Could likely beat the entire Telvanni council in 1 big battle
*Got a reputation that will grant him acces to the empires bedchamber in the middle of the night, even it the emperor is not there.
But looking over this and lore a bit more i think i know the awser.
What reason does that old wizard have to take in corpus victims with open arms? Its may sound against logic when saying it.
As the old man Divayth Fyr is, he is starting to get afriad of death. I mean, he is over 4000 years and still ageing. He might die at some point, someting he does not want. Neither of the Deadra is willing to grant him immortalety, he might lose the controll over the spell he using to stop aging, he has not found a fountain of youth.
And what does corpus do:
*Immune to disease
*You stop aging
*Make you crasy
*Heavy Deformations
When he cured Nenevarine he also tested it on 3-4 others at the same corpus stage, why? It cured Nevevarine of the corpus problems, but he kept the beenfits of it: No aging and immune to disease. If it had worked on the others and they would still keep the posetiv parts he would experiment on with several more corpus victims with the cure to find the exact stage it worked. And the chance of succes.
Then when the succes rate was high enogh, he would ask all of his daughters to give him the cure at that exact stage of corpus and then get infected.
At that stage they would force him to take the cure if he had already went nuts, and after being cured he would ascend to a immortal being.
Immortal, free of age and disease. Forget cancer, STD, and everything else. He would the move on the the next subject on his list: Getting young again(if he felt like it).
And that is my teori.
