The king ruled with a warm heart and cared for all, so Vault-Tec needed him to stay alive after the nukes go off. He was escorted to Vault 111 5 days before anyone else. He woke up when Kellog stole Shaun in the Fallout 4 game and he left before Kellog and the scientists left the vault. He now lives in Las Vegas, helping the NCR with their battle with the Legion... His legend lives one through those he has helped along the way.
