Tyr

In the early centuries after the birth of Christ, Tyr was a powerful god of the sky and war. Warriors would put the letter "T" on their weapons for help in battle.

Tyr had only one hand. In order to make the other gods feel safer, Tyr sacrificed one of his hands to the wolf Fenrir, who roamed Asgard, land of the gods. In the eighth and ninth centuries, Odin took Tyr's place as Sky god.
