Bjorn is Thor it is stated that Thor's other name was Bjorn, Bjorn ironside introduced the Motte and Bailey castle to France that is not artificial it is supernatural and is a hall modelled after Valhalla placed on the mountains of Jord the earth mother where the legacy of Odin and Jord could see far and wide like a raven seer like a Egyptian Gypsy psychic from Sun god Ra could see from up high on the pyramids to make rough predictions of the future which reminds me of the crime scene detective movie called minority report that is about preventing the murder of innocent by looking to the future.
