The Overlord of the Void
Xero the Void Crosser, the number 1 player of Ether Gate, the world's one and only virtual reality massive multiplayer online roleplaying game (VRMMORPG), has completed the seemingly impossible feat of destroying the Void Overlord singlehandedly.
After the long battle Xero finally bested the grotesque monster and removed him from existence. Among the drops of the boss a mysterious [???] item was included, it took the form a black cube which had a single question written on it: "Do you want your wish to be granted?"
