Týr is a god in Germanic mythology, a valorous and powerful member of the Æsir and patron of warriors and mythological heroes. In Norse mythology, which provides most of the surviving narratives about gods among the Germanic peoples, Týr sacrifices his right hand to the monstrous wolf Fenrir, who bites it off when he realizes the gods have bound him. Týr is foretold of being consumed by the similarly monstrous dog Garmr during the events of Ragnarök.

In Norse mythology, Ragnarök is a foretold series of impending events, including a great battle in which numerous great Norse mythological figures will perish ; it will entail a catastrophic series of natural disasters, including the burning of the world, and culminate in the submersion of the world underwater. After these events, the world will rise again, cleansed and fertile, the surviving and returning gods will meet, and the world will be repopulated by two human survivors, Líf and Lífþrasir. Ragnarök is an important event in Norse mythology and has been the subject of scholarly discourse and theory in the history of Germanic studies.
