Strangely enough, as the outside warms up, the fairy you'll end up seeing the most often is that of ice. A strange fairy already, it's rather uncommon for one to exist in a realm of lifelessness, but once you understand her thoughts it's quite simple. She prefers the warmer weather because she can be the one to freeze objects. The kind of thinking fitting for a fairy.
