- Not to be confused with Tyr's Hand.
Tyr is one of the Titanic watchers. He once resided at the Temple of Order, but is absent during the time of Loken's rebellion. It is said that no indications of struggle or guardians are present. Tyr is the only one of the Keepers left by the Titans not to appear in the Ulduar complex.
The story of Tyr slipped into memory long ago, when the young race of humans struggled to survive using the limited supplies provided to them by the parents who had abandoned them. They occasionally took to gathering around a fire whilst trying to read from scrolls telling of ancient heroes and leaders – tales from the civilization that had cast these creatures out. One of these scrolls spoke of a great leader, a paragon of order and justice, who sacrificed his right hand in a fight against an unfathomable evil. Although it was within this hero's power to fix his hand after the fighting had ended, the hero instead chose to replace it with a closed fist made of the purest silver. In this way, the hero impressed upon those who followed him that true order and justice can only be accomplished through personal sacrifice.
In Dawn of the Aspects it is revealed that Tyr lost his hand while fighting Galakrond. His attacker, known to most as the Father of Dragons, was a giant proto-drake deformed from eating his own kind, trying to fulfill ever-lasting hunger. Tyr forged an alliance with the proto-dragons: , Alexstrasza, Ysera, Neltharion,Malygos, and Nozdormu. The dragons, lead by Tyr, fought with Galakrond. When he lost his hand and later defeated him, they honed their strengths without the aid of the keeper. It was after this event that they became known as the five aspects and chose to hide. Tyr had always seen bravery in the dragons, and it was the reason he chose to fight alongside them against Galakrond. It was later revealed in this book that Tyr's original weapon was a warhammer.
The Silver Hand Edit
As one of the titanic watchers, Keeper Tyr bore The Silver Hand in countless battles against the titans' enemies. When one of his fellow keepers, Loken, fell to corruption, Tyr and his allies stole the Discs of Norgannon to investigate the extent of Loken's betrayal. Discovering the theft, Loken sent horrific monsters after Tyr's group, but Tyr sacrificed his life to fight the creatures while his comrades escaped with the discs. His hammer was lost with him somewhere beneath the land now named in his honor: Tirisfal. 
The titanic watchers Tyr and Archaedas created Truthguard when their comrade, Loken, fell to corruption. They gave Truthguard to a vrykul champion who used it to expose Loken's treachery. When Tyr and his allies later stole the Discs of Norgannon and fled, the champion stayed behind and held off many of Loken's servants. A desperate Loken sent horrific monsters after Tyr, who fell in combat. In time the vrykul champion migrated to Stormheim in the Broken Isles, where the shield was eventually entombed in the Path of Kings. 
- There is an area known as Tyr's Terrace inside Utgarde Keep, where Ingvar the Plunderer can be found.
- The Order of the Knights of the Silver Hand took their name and symbol from the myth of Tyr and his silver hand.
- The city of Tyr's Hand was also named after Tyr.
- He is the first non-dragon encountered by the protagonists of Dawn of the Aspects.
- Tyr is named for the Norse god Týr, and their history and experiences are very similar.
- His silver hand was possibly inspired by the one mentioned in the legend of Nuada from Celtic Mythology. In the legend Nuada is challenged to single combat by the champion of the Firbolg; The mighty Sreng. Nuada defeted Sreng but not before losing his Right hand to the Firbolg's sword. after the battle, the greatest physician of the children of Danu; Dian Cécht, fashioned a new hand for Nuada from pure silver, enchanting it so it worked much like his original hand. However it is just as likely to come from the Norse God Tyr who sacrificed his hand to the wolf Fenris, allowing the other gods to put the great wolf in chains. His hand was then replaced by a hand made from solid gold. A combination of the two seems to have been applied
- At one point it was suggested that Tyr may have mutated into General Vezax under the influence of Yogg-Saron. This was later proven false when Blizzard stated that Tyr was not in Ulduar when Yogg-Saron was defeated.
