John (The Visitation)

Sir John was an English squire, landowner, and father of Elizabeth and Charles.

In 1666, while he was playing chess with Elizabeth, Charles became angry with his father and went to bed. Soon afterwards, the Squire heard a shot from Charles' gun and went to investigate. He found out Charles had fired at a Terileptil and wounded it, and the Squire killed it off with his firearm. However, soon afterwards, the Terileptil android killed him, Charles and Elizabeth.
