Something from my sketchbook. She's a nature spirit that controls trees and their roots and growth. Her name is Liekkiö, and sometimes she's thought the be some kind of ghost spirit as well. Her name includes a word that means flame, liekki. It is said that you can see will-o'-wisp, virvatuli, a ghostly lights in dark places that have little population or near the water surface, and if you cause too much noise, they disappear. It's believed that they are some kind of supernatural spirits, and therefore there is a lot of myths and stories about them. In some stories Liekkiö is was also thought to be a soul of a child.
