There was something very horrific about the act of ripping yourself open, and Rowan's ghastly appearance only made it more surreal.
This was an act that could not be comprehended by a mortal's mind, but for Rowan, it was just a normal action in order to gain the advantage he wanted.
Rowan's ruthlessness has become part of his innate nature.
The creature receiving this boon almost went mad with joy as it chittered loudly, and Rowan groaned as he fell on one knee.
This body was powerful, but its recovery prowess was stifled by him and so, the pain he was feeling from a wound that was this massive was billions of times more severe than a mortal could ever comprehend, even a god might go mad if they received such a wound.
Rowan understood that if he wanted power, he would have to pay the price, and the pain was a simple and cheap price for him to pay.
