She is close to her family but is an outcast at school. Unlike her blue-eyed family members in the Celendis clan, Elly is green-eyed with long, curly black hair that always seems messy, which is unusual for sleek-haired elves. She is also smaller and less agile than most elves, and she has very little affinity with music. She is intrigued by all things related to the human realm, and wishes she could explore Gaya which has been sealed off for a hundred years. Elly is a bit like a 'tom-boy' in that she detests the colour pink and anything too 'girly'.
