Beowulf says goodbye to King Hrothgar and sails back to Geatland. Hygelac and his family are killed, and Beowulf becomes the King of the Geats. He is an honest warrior-king, rewarding his loyal lords and taking care of his people.
But one day, Beowulf finally meets his match: a dragon, woken by a thief stealing a drink, begins attacking the Geats, burning villages and killing people. Beowulf takes eleven warriors to the hill for a final face-off with the monster. When they see the dragon, all but one of the warriors run in terror. Only one man, Wiglaf, remains at Beowulf's side. With Wiglaf's help, Beowulf is able to defeat the dragon, but he is wounded.
After Beowulf's death, the Geats built a big funeral for him, piled with treasures. Once the fuel burned down, they spend ten days building a huge mountain as a statue to their lost king.
