Tyr is the god of war, but more than anything he is the god of law and justice. There are many kinds of evidence that show that Tyr was once one of the most important gods to the Norse and other Germanic people. Warriors used to invoke Tyr for victory in battle. Tuesday is named after Tyr (Tiw – Tiwesdaeg). In an Eddic poem “Lokasenna”, Loki insulted Tyr by saying that he could only stir people to strife, and could never reconcile them. That happens after Tyr lost his hand to Loki’s son Fenrir (“fame-wolf”). Fenrir is one of the three children Loki had with giantess Angrboda, and he was so large and threatening (not to mention the Voluspa – prophecy that he will bring upon the Ragnarok) that when the Aesir decided to raise him in Asgard (for the time being), Tyr was the only one who had the courage to feed him. And thus they developed a friendship, him and Fenrir. It is said of Tyr that he was so trusted by the races of the Nine Realms that even Jotunnar (the Giants) trusted him, even though they hated all of the Aesir, they saw him as an ally. Due to the prophecy the Aesir feared for their lives, and thus Odinn came up with the idea to bind Fenrir in fetters from which he couldn’t escape, one of the signals that the Ragnarok is upon them, was the freeing of Fenrir from his binds. So it happened that when Fenrir laid his eyes on the chain that would eventually bind him, he was suspicious, and declared that he would only allow the gods to put it around him if one of them would stick an arm in his mouth as a pledge of good faith. Only Tyr, his friend, was willing to do so. When Fenrir found himself unable to break free, he bit off Tyr’s hand at the place that is now called the wolf-joint (wrist), and thus Tyr became one-handed, and is not considered a promoter of settlements between people. With this sacrifice, Tyr did not only procure the salvation of the gods for the time being (or played a crucial role in self-fulfilling prophecy, whoever you want to observe it) but he also regularized it: he renders legal that which, without him, would have been pure fraud. Tyr’s energy is suitable for courtrooms, for all matters concerning law, for battles that you know in your heart that are just, and that justice is on your side. Tyr is god of law and god of justice, so make sure that when you evoke his energy you are on the right side of the justice.
