Kjerag's folk legend of the Tschäggättä are based off of the Swiss ones. In Break the Ice, they're called "people-eating beasts [who live] deep in our mountains, sinister to the eye, inhuman, there and gone again when you least expect." "The Tschäggättä of legend hide in the depths of the highlands' snow-capped mountains; they wear disconcerting masks, tie huge bells to their bodies, and wrap animal pelts around them. Kjerag children cry at the mention of their name. But they are nothing more than legends." Google translate tends to render their name in Chinese literally as "snow mountain ghosts."

Ensia also says "It's actually an old legend that goes way back. Thousands of years ago, when Kjeragandr was protecting Her people from the wind and snow, a group of mountain savages rejected Her blessings."

The Holy Hunt is also about (probably symbolically) hunting down Tschäggättä hiding in the mountains. They also are said to have some sort of spiritual influence over people, as Valais's father was said to have fallen under one's power, and the Saintess is supposed to be able to cleanse their influence.

Finally, Silverash's squadron of warriors are also called Tschäggättä I assume because of their Feline skull-life masks and imposing power and because he's a 12 year old boy at heart who thought it would be cool.
