If we examine Narnia, we find elements like The White Queen corresponding to jotun maidens , or the dragon-prowed Dawn Treader matching to the magical saga drakkar longship Elliði , or greedy Eustace Scrubb turning into a dragon just as gold-hoarding dwarven Fafnir turns into a hoard guarding wyrm.
