If you've read Gameknight999 vs Herobrine, than you would know that Gameknight and his father just barely managed to destroy Herobrine before he escaped into the physical world. But what if they hadn't? This is my interpretation of what would've happened if Gameknight wasn't able to stop Herobrine from escaping. (btw, i changed the chapter where they fought a little by adding another character, so plz don't get mad.)
