According to some of the ghosts at Galloper's Keep, the man who would become Galloper Thompson was shunned by all horses ─ all but this mare. It is said he brought her from the east and that she posessed no trace of Aideen's Light, which made the druids of Jorvik take her away from Thompson. He presumably went after them and reunited with his horse after getting a revenge on the druids.
