The Legend of Randidly Ghosthound.

Gore Profanity
As the system initializes, the world shifts. Geography is rearranged and mixed, and levels and stats are instituted across the globe. On that night, one young man was walking through an underground tunnel, his mind on the small problems of his easy life. Because of his location during the shift, he starts in a dungeon far above his level, with no knowledge or teacher, or Newbie Village to guide him. Without a class, he struggles simply to survive in this world changed by its new connection to the Nexus.

But struggle he will, for he is Randidly Ghosthound, and this is only how his legend begins...
