About him:
He is a very intelligent and curious creature that loves to pass his time trying to get better in medicine. He is committed to cure all the different kind of ills, but there is a problem on this, he cannot open bodies because it is a sacrilege, but his curious being and the will to help the others, made him to challenge the laws and study what is inside of corpses.
A curious thing about him is that he even can use his snake poison as an ingredient for some medicine.
He grew in a monastery where he could see the monks caring for the sick.
