Nyalmot is a demon in the series.
Nyalmot is a large primate-like creature allegedly living in the Himalayas. It reputedly grows to a height of fifteen feet and leaves long, four-toed tracks in the mud and snow. Bernard Heuvelmans believed the nyalmot could represent a relict population of Gigantopithecus.
The first documented sighting of a Nyalmot occurred in the Himalayas in 1937; a small expedition had come across a group of "twenty-foot" creatures, standing in a circle and chanting, as if in a religious ritual. One of them was beating a hollow tree trunk, as a drum; on their faces was a sad kind of expression, and one of the adventurers later commented that "there was nothing...animal about them."
"The largest species of yeti (snowmen), said to be over four meters tall. They are violent by nature and eat livestock like sheep. Covered in fur except for the face, it has long arms and can walk upright like a human. Note that the small species of snowmen are the Raksi-Bombo, and mid-sized are Rimi."
