VOID

VOID is a blank world that exists in a separate dimension or reality than our own. An eldritch being is master of this realm and captures beings, objects, places, monsters, and matter from across the universe and pits them against each other for its own amusement. Once trapped, it becomes impossible to leave VOID - the only thing left is to do is survive.   The story follows Finch, a dude from Earth who is thrown into VOID, and has to learn how to survive the threats inside. His only hope to escape is a girl named Zetta who is collecting mysterious relics said to have the power to exit VOID for good.
