This unicorn (an NPC from our recent online pen and paper rpg of Tails of Equestria) has been dubbed “Maretiana” by most of the ponies of Trottingham, refering to her original homeland of Maretonia (and outside the game world it can also be read as a reference to “Mortianna” from the 1991 Robin Hood movie). Some would just call her the “crater witch” since she is living in a meteor crater off the shore of Trottingham, kept dry from the surrounding water by a magical sphere. Technilcally said crater constitutes a country of itself. It is a bit of a refuge for this pony who at one point has greatly abused her two great gifts (illusion magic and the ability to get glimpses of the futures). I have written a little more elaborately about this in the text accompanying this animation of a magic illusion she had cast during our game.
