Death’s Herald

Death’s Herald is a passive monster that spawns in The Epilogue, after killing 10,000 monsters after the death of The Phantom. Getting too close to him, or interacting with him in any way, such as shooting at him, will cause him to start to shudder and screech, the whole screen turns black, and the Wall of Death wakes.

He appears as what looks like the guide, but his skin is obsidian black and he has a hood over his head. He is 3 blocks wide and 9 blocks tall, three times the size of the player. He holds what appears to be a glowing purple Terra Blade, and he leeches all the color from around him, so that in the area of about 50 blocks around him, the tiles are black and white and grey, except for him.

Story
He used to be a hero, just like the player, but The Phantom leeched out his life force when he tried to destroy it. It sent the former hero to Limbo, where the Wall of Death used reside, taking power until it was strong enough to destroy the world. The Wall of Death’s spirit, who was the seventh spirit, the Death Spirit from The End, which the player could not find and could therefore not destroy, took control of the hero’s body and sent it to the earth to tell the Death Spirit when the earth was weak enough to destroy. The possessed hero was drawn to the enormous amount of death that the player had unleashed, and saw that the player had destroyed everything that could have stood in the way of the Wall of Death. He sent this information to the Death Spirit, and the Wall was unleashed.
