Ro'Maeve has the same thing at the Qu[tab] spring. A fire spirit'll show up with Fenrir's name. It doesn't do anything. It's the server regurgitating things, mostly.
However, they do not show up in areas without weather. So I guess that leaves Jeuno, Sandy and surrounding region, Bastok and surrounding region, and Windurst and surrounding region glitch-free for the most part.
