WARNING this fiction will have heavy elements of gore, brutality, torture, cannibalism and other dark topics. Not for the faint of heart, you have been warned so read at your own risk of being offended. Don't blame me. Also the CYOA does not being to me and I am using it as a reference, that being said this content is written by me from my head/imagination. This is fiction and resemblances to the real world is just a coincidence.
