About this AUEdit
The Big FourEdit
Since Jack was officially described as an Ice Elf by the writers of Rise of the Guardians, he could easily be featured as an Elf that exists in the world of Dragon Age. His ice powers that could can use through his staff as well as with his own two hands, could even make him a Mage. That is a human or an elf.
Since Rapunzel use magic through her hair (before it was cut) could make her a Mage, that uses her magic to heal people.
Elsa's ice magic easily makes her a Mage.
