When the warriors in Herot were playing music and being cheerful Grendel was in pain with it happening every day. Grendel came up at night while everyone was sleeping to see what the men would do when their drinking was done
I'm so thankful for Beowulf
Grendel found them sleeping not expecting anything and slaughtered them. He had a quest for evil and he came back the next day. It was one against many and Grendel won and the warriors the ones that survived fled far away from Herot.
You shamefaced jackals lose everything for not fighting with your king
Beowulf hears of Grendel and comer to Denmark to kill him. Once he gets there he is questioned of his ability to be the hero. But he proves he is strong enough to handle it.
Grendel and Beowulf battle in Herot during the night they fight fair with no weapons. Beowulf succeeds by walking away with Grendels arm. Hrothgar is grateful of Beowulf for saving the kingdom and puts the arm in the trophy case.
Beowulf defeats Grendel's mother he rules for 50 winters until a dragon starts to attack the town. And since Beowulf has aged he can not fight the dragon with his bare hands he finds a sword made from thee gods.
Beowulf ends up getting injured trying to kill the dragon. He ends up dying and they have a burial at sea and bury him with the dragon’s treasure. Wigalfs ends up taking over and punishing the warriors that did not stay to fight with their king.
