My children are and always shall be my greatest accomplishment.
Sleipnir is a mighty 8-legged stallion—the great war-horse upon which the All-Father rides to battle. He is intelligent, curious and kind, and a stalwart warrior. He calls me “mother”, which is accurate because of a very long story which apparently has been terribly contorted and spread all over this internet of yours.
Fenrir, my lupine child, is a great wolf with a magnificent and terrible destiny (we are working on changing that). He is currently in captivity, and all my pleadings can do nothing to change the mind of the All-Father towards my beloved son.
Jormungandr is my third son. He is a serpent of mighty size, and he was cast into the oceans which surround Midgard by the All-Father. Midgardian myths say that he is long enough to span the entire earth, so long that he can grasp his tail in his own mouth. It is said that if he ever was to release his hold on his tail, Midgard would come to an end.
This is all non-sense, of course.
My dear daughter Hela is a child with who literally stands with one foot in Hel and one foot in the living world. She was cast out of Asgard by the All-Father as well, but she was given stewardship over the land of Hel, and she reigns there with mercy, wisdom and justice.
