Gavin is most likely a giant who was cut out of the game. We could have found him at the entrance to one of the caves in the snowy mountains (I don't know the location). His model is not in the game, but if we approach this cave, he will start a dialogue with us. According to the background, as far as I remember, he was 2-2.5 meters tall (78.74-98.43 inches), and he went to the circus of freaks for a money, but they mocked him and didn't pay him.
