Tyr

And the god said: 'There is also an As called Tyr. He is the bravest and most valiant, and he has great power over victory in battles. It is good for men of action to pray to him. There was a saying that a man is ty-valiant who surpasses other men and does not hesitate. He was so clever that a man who is clever was said to be ty-wise. It is one proof of his bravery that the Aesir were luring the fenwolf so as to get the fetter Gleipnir on him, he did not trust them that they would let him go until they placed Tyr's hand in the wolf's mouth as a pledge. And when the Aesir refused to let him go then he bit off the hand at the wrist, and he is one-handed and he is not considered a promoter of settlements between people.

Tyr is an Aesir of war, victory, wisdom and promise-making.
