Khyah, also known as Khyā, Khyāk or Cyak, is a mythical humanoid creature of Nepal that appear in the form of a fat, hairy, short ape-like being. Khyahs appear in children's stories popular in Newar society.
A friendly Khyah fills the home with goodness while bad ones bring trouble. A white Khyah is believed to bring good luck while a black one can create problems. Encountering a Khyah can make one ill. To banish Khyah, an exorcism dance is held, and humorous dances including acrobatics are performed as well.
In Newar culture, Khyahs attend to Lakshmi, the goddess of wealth, and pictures of the deity show them guarding overflowing bags of coins. Household Khyahs usually dwell in the attic and dark storerooms. They are said to fear electric lighting.
"Origin: Nepal. A Nepalese monster of the night. It's covered in black fur and its red tongue hangs out of tis mouth. It's said to be benign to humans. In fact, its acrobatic dance drives out evil spirits."
