[Other] Hiisi is a Finnish forest-god whose cult was especially spread throughout eastern Finland. He was considered the guardian spirit of the sacrificial grove; and was called the son of Kaleva and believed to be a giant of ancient times. Later he was degraded to a (evil) wood spirit, and his name even became a synonym for "devil". He is beardless and ugly, has lopsided eyes without eyelids, and is dressed as a scoundrel.
