The Tyranny of Dragons: Dawn of Heroes
Grimjaws, the Maimed God, the Evenhanded
Tyr Grimjaws, Tyr the Evenhanded, Wounded Tyr, the Maimed God, the Blind, Blind Tyr, the Lord of Justice- all of these names speak to the nature of the Faerunian god of justice. Tyr appears as a noble warrior missing his right hand, which he lost to Kezef the Chaos Hound in an act of bravery and sacrifice, and with his eyes wrapped in cloth to signify his blindness, caused by a wound dealt to him by Ao when he questioned the justice of the Overgod's actions.
Tyr’s followers devote themselves to the cause of justice, to the righting of wrongs and the deliverance of vengeance. This devotion isn’t necessarily concerned with equality or fairness, but rather the discovery of truth and the punishment of the guilty. Those who favor Tyr tend to be stiff-necked about matters of theology and laws, seeing things in terms of black and white. Tyr’s credo of lawfulness and honesty is a demanding one, and his priests remind the faithful not to hold in contempt others who can’t live by it— it wouldn't be an honorable calling if everyone could muster the strength of will to follow it.
Many orders of knighthood are devoted to Tyr, including the Knights of Holy Judgment and the Knights of the Merciful Sword. Such knights— as well as judges and priests, clerics, and paladins who worship Tyr— sometimes wear thin strips of diaphanous cloth over their eyes to remind others of the blindness of justice.
