While her official name is Snow Flurry, she normally goes by Anivia. Her name is based on the League of Legends champion Anivia, a Cyrophoenix. She lives in the Crystal Empire, though she is not a crystal pony herself, but looks up to them, and is envious of their crystalline forms. She spends most of her time in the Crystal Mountains exploring and playing with the wild animals there. Her cutie mark represents her knack of controlling the icy weather of the north, and she helps maintain harmony in that region.
I made this pony for a ponified pathfinder game, and felt I might as well adapt her to the current world of Equestria as well, and vector her. In my Pathfinder game, she specializes in Ice magic through manipulating the weather to hinder her foes.
