Tergrid

Tergrid is the god of fright from Kaldheim.

Description
Tergrid is an accomplished warrior whose shadow has a terrifying life of its own. She tries her best to live a normal life, despite the menacing ﬁgure that follows her everywhere. It appears as a towering hooded ﬁgure that never speaks, looming behind her or occasionally wrapping its shadowy ﬁngers around her neck. Tergrid pretends it isn't there and lashes out in anger at anyone who acknowledges its presence.

Unfortunately, she has the unnerving tendency to blurt out some terrifying omen or threat that cuts conversations short and leaves her listeners rattled for days.

History
Tergrid and her sister Esika came into being when Alrund used runic magic in an effort to commune with the World Tree.

When Tergrid was a baby, she didn't just cry. She wailed in some unknown language that caused temporary madness in anyone who heard it.

When she was four years old, her shadow came to life and attempted to strangle her, but even as a young child she was able to battle it for days until she bent it to her will.

Trivia

 * Tergrid is similar to Nótt, the Norse goddess of the night and Hel, a legendary being who is said to preside over a realm of the same name.
 * She is also similar to Odin. Odin had the power to lay bonds upon the mind so that men became helpless in battle, and he could also loosen the tensions of fear and strain by his gifts of battle-madness, intoxication, and inspiration.
 * Marvel Comics' god of fear Cul Borson could be another source of inspiration.
