And Heven help whoever try’s to hurt her. For you will suffer his wrath. Also have you thought about give him a dragon Blood, Heart, Lungs and Soul? The Soul could be from Skyrim, The Lungs from Harry Potter, The Blood from GoT/SoFI and the Heart from Fate. This will grant him nearly unlimited magical energy as well as unlock the Thu’um. Plus other dragon related things you can choose.
