From the Journal of Notch: “Before Herobrine was considered an Urban Legend, he was real and had a life. His disturbing presence, causing havoc and widespread panic was because he was betrayed and left for dead. Some say he survived and bring his vengeance with him to the living.”
Betrayed by his own kind and left for dead on a desolate island, Herobrine fights for survival against hostile mobs and becomes more powerful and dangerous than ever before. Soon "other players" from throughout the Minecraft universe descend on Herobrine only to find themselves pawns in his greater scheme for revenge. With his enemies’ right where he wants them, Herobrine unleashes a vicious attack of vengeance before returning to his fortress to save it from destruction.
