Not sure I understand the story...
Okay so Fallen Kingdom happens, Herobrine uses his army to make the kingdom get blowed up. King loses his wife but his son survives and is found by a villager, and Take Back the Night Happens. The son goes on a quest for revenge and kills Herobrine. Later, Pieces happens, and the pigman army finds out they need the Nether Star to revive Herobrine. They take the Wither to the Overworld so that the son can kill it, and then they steal the Nether Star once the Wither is dead. The son travels back to the kingdom (for some reason) and is reunited with his dad. Meanwhile, the pigmen use the Nether Star to turn the pigman king into Herobrine.
Was that right?
