Sanctum: The White Trials [LITRPG progression]

The sanctum; A place of unknown origins, a place outside of space and time. Governed by entities with no names, explored by those with incomprehensible power. No one knew about its existence until a poor guy was stolen from his home and thrown into the pits of the White Trials. That unlucky soul belonged to Gray.  No, he wasn’t strong, nor was he a genius. Sure, he could lose some weight, maybe get his mental health in check, you know, the usual fare for someone who walked his path of life.  Yet, uneventful, his past was not. He’d gone through his fair share of mysterious events; like the time when a bullet drilled through his skull, creating a new hole inside of his head, and then, he… came back alive? He didn’t know what to think of it, so he assumed it was just a vivid dream; A premonition that saved his life.  One fateful night, right before he was about to sleep; A bright azure screen appeared, altering the course of his life forever.
