Beowulf sailed to Denmark to pledge his protection to Hrothgar, King of the Danes, whose hall had been rendered uninhabitable by the ravages of a devouring monster in human form named Grendel, who dwelt in the wastelands and under cover of night forced entrance to the hall and slaughtered the inhabitants.
The Danes retired to safety while Beowulf feasted in the hall and waited to face Grendel alone.
Beowulf tore his arm from his shoulder, mortally wounding him and tracked him to the lair of his mother the Sea Hag and slew her as well after she had retaliated for Grendel's death.
Richly rewarded by the king he returned home to a throne of his own and ruled prosperously for 50 years until he did battle with a ferocious and terrifying fire breathing Dragon. He overcame it but suffered a mortal wound in the struggle.
Amid great lamentation he was placed on a great funeral pyre and burned and the Dragon's treasure was buried along with his ashes.
