Osiris' Element

Osiris's element is sky, despite being an earth pony. This ability, through use of his Talisman, has giveinf him the ability to fly in dire circumstances. 

Osiris absolutely adores the sky in its beauty, but hates not having his hooves on the ground, and as a result has mixed feelings about his element. He also doesn't think he flies well,  due to lack of experience, despite being as good as an average Pegasus
