Wendigo, it was a word that hadn't been mentioned in a while and it had long shifted to the back of Quinn's mind, but suddenly all of the bad thoughts came rushing out his head as the system had said those words. The wendigo was one of the evolution's a ghoul could evolve into.
It was one of the options that Peter was able to evolve into but instead, he turned into a Wight.
They were similar to Wights with their amazing healing capabilities and strength, but at the same time vastly different. They showed no signs of intelligence and were unable to speak any words. They were detached from any emotion, only feeling one thing, hunger. Their hunger was far greater for flesh than a Ghoul or a Wight. While they did it out of survival, the Wendigo's did it out of addiction.
