The original Herobrine seed has finally been found! [Minecraft@Home]
Ever since the first Herobrine Creepypasta, people have faked his world multiple times. So we used our seed cracking knowledge from Pack.png and the Minecraft panoramas to find the seed once and for all!
More information, including the seed and coordinates: https://minecraftathome.com/herobrine

Disclaimer: Herobrine isn't (and never has been) part of vanilla Minecraft. Do not expect to find him here.
