We all know Herobrine, right? But no one really knows his true story. This is my opinion of his story.

Herobrine was a regular, new player to Minecraft, and Minecraftia. He had a girlfriend and a large mansion. One day, he decided to videotape his adventure mining. We all know Music Disc 11, right? That was his tape. He mined, but then he got lost in a mineshaft. He coughed, and opened his Crafting Recipe Book to find out how to make a map. But suddenly, he heard strange footsteps. He ran with the tape and forgot to stop recording. The unknown monster gave him cursed diamonds. He was so relieved that that didn't kill him. The tape didn't record his path to becoming cursed, just his adventure in the mineshaft.
Three days later, he made a sword out of the cursed diamond. He PvPed a player with it. But the sword had hidden costs. The following day, his girlfriend disappeared. He was so miserable he stabbed himself with the sword. But it made him cursed, which meant he failed to commit suicide. He became cursed. He was so miserable he wanted revenge over that player he killed. Now, he hunts, and looks for players so he could find that player. This is why he stalks us. He also makes weird structures because he tortures players in these structures, and jails them to live a miserable life.
If you have anymore cool ideas for Herobrine's mystery story, post it in the comments. I can gladly rewrite this later.
