Minecraft. Just a simple game, right? A few colourful blocks, for some silly entertainment? Wrong. So very, very wrong. Minecraft is a thriving, hidden world, a bizarre place of creation and survival. And, living in the Realms that make up this land - Ocean, End, Nether and Overworld - are dozens of living creatures; a wild wolf here, an enderman over there. And, living alonside them all, is a being that they all know. The Realmer. Over thousands of years, they have enjoyed a long reign of peace, despite the occasional struggle. But then a deadly and ancient enemy, from the time when Gods roamed the Overworld, finally breaks free of his chains, and starts to tear apart the world they know and love. But, even as their world falls into chaos, four friends who hold the fate of their world in their hands will do anything to protect their home. But there's just one problem. They have no idea where he is. And all they have to go on is a single name. He calls himself Virus.
