The Void is part of Minecraft. When players or mobs go in there, they die. Malacoda was the first in the series to die in the Void. In Confronting the Dragon, when his and Erebus' army are in the End, Erebus sends his Endermen to drag Malacoda into the Void until he dies. Later, Gameknight999 and his friends travel to The End to rid themselves of Herobrine (as a pig). Herobrine is thrown into the Void and he is presumed dead. However, he comes back as the Ender Dragon.
