The Dark Powers

[Tirned Tinnu]

I have often heard the members of various bboards comparing Morgoth to Loki:

Loki is one of the major deities in the Norse pantheon. He is a son of the giant Farbauti ("cruel striker") and the giantess Laufey. He is regarded as one of Aesir, but is on occasion their enemy. He is connected with fire and magic, and can assume many different shapes (horse, falcon, fly). He is crafty and malicious, but is also heroic: in that aspect he can be compared with the trickster from North American myths. The ambivalent god grows progressively more unpleasent, and is directly responsible for the death of Balder, the god of light.

Loki's mistress is the giantess Angrboda, and with her he is the father of three monsters. His wife is Sigyn, who stayed loyal to him, even when the gods punished him for the death of Balder. He was chained to three large boulders; one under his shoulders, one under his loins and one under his knees. A poisonous snake was placed above his head. The dripping venom that lands on him is caught by Sigyn in a bowl. But every now and then, when the bowl is filled to the brim, she has to leave him to empty it. Then the poison that falls on Loki's face makes him twist in pain, causing earthquakes.

On the day of Ragnarok, Loki's chains will break and he will lead the giants into battle against the gods. Loki is often called the Sly One, the Trickster, the Shape Changer, and the Sky Traveler.

As such, Sauron would have to have been one of Loki's followers, if not one of his sons...
Does anyone have information regarding them? I seem to recall something about them being like evil sea creatures...or am I mixing in Greek/Roman mythology?

Also, though I have not read them in their entirety, I believe there is a character in the Finnish sagas that is similarly ?evil?
Can anyone shed some light where I have failed? [img]smilies/confused.gif[/img]
