This is the dark version of Huldra, darker than the original. You can see that she has a darker side that appears around the lips.
Huldra is a mythical, beautiful female creature you can encounter in the mountains or the deepest of forests.
According to Norwegian tales, she lives in the Norwegian mountains and underground and entices men with appearance and charm. Huldra also steals children and exchanges them for their own. These children are called “swaps”.
Huldra appears to the public for better or worse. She can get you in danger and unhappiness, or she can help and comfort you. Huldra can lure and obtain men hiking in the mountains, and in some tales and anecdotes, she also marries human souls.
