Living in a snow-slicked bog, at a lake that always looks on the brink of freezing, lies a sinister looking equine creature; if she gives someone the chance to look at her, they would notice a broken horn on her head. Of course, no one gets a good look at her; all the rumors anyone can say about this mysterious creature is that the freezing cold water at the specific lake where she lives will sometimes shift, revealing a vaguely horse shaped disturbance, not even a silhouette of the creature due to how murky the water is, and those who approached were swiftly pulled under, never to be seen or heard from again...
