In your last quest, Herobrine dragged you into a portal that sent you into a realm beneath the darkness of the Void in the End Dimension. You escaped, but not before you came face-to-face with a far worse danger- Null, the creator of Herobrine and Entity 303.
As you fled the Land of the Void, he swore to destroy the Overworld and torment its people forever...but you jumped through the portal, assuming it was nothing but an empty threat.
When you emerge back to the Overworld, however, you realize that it has already fallen....the Century Portal has transported you a hundred years into the future, where Null has already brought the Apocalypse of Nightmares to Minecraftia.
There is only one way to reverse time and save your world from this horrible fate.....you must find the source of the dark Contagion that has overswept the land, known as the Heart of Corruption. You must destroy this Heart, but it is hidden deep inside a world of deepest fear, a land of agony and terror...
You must once again face......The Nightmare Realm.
