you are the Nymph of Durmstrang. you are Viktor Krum’s twin brother. Durmstrang(those of age) go to Hogwarts for the Triwizard Tournament. everyone else makes their entrance, then Headmaster Karkaroff and your brother bring the fairy-garden that you're in, into the great hall. Everyone in Hogwarts, including the students of Beauxbatons, have heard of the Krum twins.

(your looks: silvery-blonde hair, with green streaks, and a flower crown, blue and gold eyes, a yellow uniform, with a blue tie, nymph ears, and vines growing on your body)
