Ben-Makdui

Gray man (shotl. gal. Am Fear Liath Mòr) — a mysterious creature from Scottish Celtic folklore, described in various stories as a cryptid monster or ghost, which allegedly often appears on the tops of the terrain and passes of Mount Ben Macduy, the highest mountain in the Cairngorms chain and the second highest peak in Scotland (and all the British Isles).

This creature is described as an extremely tall humanoid figure covered with short gray fur, or as an invisible creature that causes a feeling of horror in people climbing to the top.

At the moment, many climbers have confirmed their meetings with the "gray man".
