Grettir's Saga

Grettir's Saga, the formal title of which is Grettis saga Ásmundarsonar, tells the complete life story of Grettir Ásmundarson. After the fashion of the earlier Icelandic family sagas its first chapters deal with the lives of his father and grandfather, Thorgrim Grey-head, along with his great-grandfather, Önundur Tree-foot, who lost his leg on the losing side of the battle which united Norway. He then fled to Iceland, beginning the family history which would lead to Grettir's own exploits. 

At a young age, Grettir kills a man he suspects has stolen his food, and is summarily banished from Iceland to live as an outlaw for three years. He travels to Norway, where he fights Kar the Old, a draugr -- a sort of re-animated corpse that guards treasure in its burial mound. He then defeats bears and berserkers, before fleeing Norway and returning to Iceland following the murder of a man for an insult. 

Upon his return, he fights another draugr named Glámr, and despite his victory, is thereafter cursed with bad luck, a life of outlawry, and early death, and to always become weaker, never stronger. Shortly after, he accidentally causes a fire which kills a hut full of people. At the next Althing, he is voted an outlaw in absentia, and upon his return is forced to a life outside of proper society. 

After nineteen years being hunted and battling numerous enemies, his family petitions to have his outlawry ended, claiming that a man cannot be an outlaw for more than twenty years. It is decided that his outlawry will be lifted when he serves a full twenty years, causing his enemies to redouble their efforts. Using magic, his enemies cause Grettir to mortally wound himself before his outlawry ends.
