In Norse mythology, Thor or Donar is the god of clouds, thunder and fertility and, like all other Aesir, he died during Ragnarök. Only Odin was above him and more feared. He was the son of the Aesir Odin and the human Jörd and therefore the blood of Asgard and Midgard flows through him. Thor's realm in Asgard is called Thrudvangr. There he lived with his wife Sif in the largest palace in Asgard, "Bilskirnir".
Thor's most famous weapon was his divine hammer 'Mjölnir', which was the source of his power. He also possessed the 'Megingjörð' belt which further increased his power. However, his trademark was the thunder that announced his arrival when he used his goat-drawn cart. There are many legends about his heroics, such as his first fight against the Midgard Serpent, his feud with the frost giants, or how he and Loki used a trick to retrieve the stolen hammer Mjölnir from Trym the giant.
Like all Aesir, Thor met his end during Ragnarök, the fate of the gods. He fought the Midgard Serpent and won, but then fell into its venom which eventually killed him.
