Name: Universal Insanity
Synopsis: After escaping a highly advanced alien research facility, Lucius mysteriously found himself alone, stranded on a ruined version of Earth, filled to the brim with monsters.
He spent centuries living in that world with only his highly advanced full body armor suit, surviving by eating monster flesh. His previously black hair turned white, and his sanity broke down countless times.
While living in that world, he discovered that the aliens did something to his brain, and that brain had numerous abilities, such as manipulating his own mind as if he was fine-tuning a piece of software.
On one particular day, he was tired of everything and decided to "sleep" for an unknown period of time, sort of like an indefinite hibernation. But suddenly, he was dragged into another world.
This world was a medieval fantasy world. Thus, realizing that he was mysteriously set free, it was finally time for him to do the things he wanted.
