Tyr

Known as Anachtyr in Calimshan, was the lawful good greater god of law and justice in the Faerûnian pantheon and leader of the coalition of deities known as the Triad. The titles of The God of Justice allegorized his nature to his followers. He bore his title of the Maimed God for his missing right hand, lost in an act of bravery and self-sacrifice and his title of the Even-Handed referred to his position as the god of justice, though was also seen as dark humor. The wounded eyes of the Blind Overlord meanwhile were seen as symbolic of "blind justice" and the cost that sometimes came with living a lawful life. His symbol however, balanced scales upon a warhammer, truly symbolized his nature; justice upheld with armed vigilance and benevolent might. An interloper deity, Tyr, known as the One-Handed across the Outer Planes, was the same power as the god of the same name in the Norse pantheon, although in the Realms he was worshiped only as a god of justice and not as a god of war. As the only Norse power worshiped in Faerûn, if a cleric of the Norse pantheon came to Toril from another world, he or she would be granted spells through Tyr.
Tyr was strong-spirited and noble. He was considered the bravest and the most honorable of all the Aesir of the Norse pantheon. He was primarily concerned with the punishment of wrong-doers and the general furthering of law and good in the world. Tyr hated duplicity, trickery, rule-breaking, and wanton destruction. He likewise hated lies and the breaking of oaths and was disgusted by persons who earned from such things. For his own part, he never would break a promise. Tyr urged the establishment of moral and ethical codes for sentient beings in all lands.

Tyr was a fair judge, but he was hard to understand to those outside his faith, as they more readily perceived him as a stern and rigid punisher. On the other hand, he was seen as a brave father-figure to his followers. In truth, he was well aware that a lawful utopia would never be possible in the imperfect Material Plane, yet this did not stop him from trying to make the world a better place for his mortal followers. He wanted his followers to see themselves as a "perfect family", not made of perfect individuals but rather of members who tried and wanted to be perfect, who acted out of trust, courage, and love toward each other. His knowledge that such a dream would never be achieved among the mortal realm filled him with genuine sadness.
Tyr was at first more willing than many other gods to manifest in some form or other to his followers, because of his fierce feelings of fatherly protection toward them. By the late 14th century DR, however, Tyr had tired of appearing in the Realms and began limiting his appearances to cases with important repercussions that were not obvious to mortals. Besides his avatar, Tyr might send an intelligent war dog as a representative, or he might use a resounding gong, a choir of male voices, or a floating warhammer to express his will. The colors blue, white, and purple were considered sacred to his followers.
Tyr was said to be able to instantly perceive any thief coming near him and to see invisible objects and persons. He could create magical items that also bore such powers. He always knew anyone's moral and ethical viewpoint and could detect any lies. Tyr was immune to all illusions, fear, or magics affecting one's emotions. If casting magic, Tyr never used damaging necromantic spells. His spells from the law sphere were three times as powerful as normal. Tyr was powerful enough to grant his clerics their spells even if they traveled to another crystal sphere. However, not all deities were powerful enough to do this, and if one of his clerics found her- or himself in the presence of a cleric of one of these lesser powers, Tyr would only grant spells of the same power as those granted by the other weaker cleric. He did this out of a sense of fairness. As god of justice, Tyr could foretell any injustice up to six months before it occurred and felt the pang of that injustice for six months afterward.
Tyr's longsword was named Justicar. It was said to have been a gift either from Tyr's predecessor or from Lord Ao himself. It was crafted with the aid of Mystra. Tyr's warhammer was especially disrupting to undead.
Tyr was the head of the group of deities known as the Triad. The two other gods who made up the Triad were Ilmater and Torm. Torm served as Tyr's war commander and was known as the "good right hand of Tyr." Among the greater deities of Faerûn, Tyr was the only one of lawful good alignment. Along with the Triad, Tyr was close to Lathander. He opposed the deities Bane, Bhaal, Cyric, Mask, Talona, and Talos.
The highly organized church of Tyr was strong in the more civilized lands of the Realms. They were known for never refusing service or aid to the faithful when they were in distress. The blind god ruled over law and justice, encouraging valiant acts from his followers and relentlessly pursuing oathbreakers. Followers of Tyr were expected to show fairness, wisdom, and kindness to the innocent. Tyrrans never enforced an unjust law. After the Time of Troubles, an entire decade passed where Tyr forbid specialty priests within his church. The clergy believed that he wished to ensure that no members of the faith were treated with greater favor than others. After other churches mocked them for this, Tyr established special orders of priests beginning after the Feast of the Moon in 1369 DR.
