Grendel
Grendel's Claw (Arm) & Hroghgar's Closest Friend
12 years
Grendel's mother takes revenge for her son's death by killing one of Hrothgar's trusted advisors in Herot. She then takes Grendel's arm, which was hanging as a trophy in Herot, and retreats back to her underwater lair.
The warriors of Herot are celebrating and listening to the bard's song about the creation of the world. This angers Grendel and in his first attack he kills 30 sleeping men.
Grendel hates Herot because he feels rejected and isolated from the celebrations and joy happening there. The noise and revelry of the mead hall remind Grendel of his own loneliness and he sees the people in Herot as a threat to his existence. Grendel's violent and chaotic nature also fuels his hatred towards the hall and its inhabitants.
The creature Grendel is the one who taunts Beowulf and the warriors in Herot. Grendel terrorizes the mead hall and its inhabitants, causing fear and destruction until Beowulf arrives to defeat him.
For goodness sake, do your homework and read it! It'll make you a better person, honest.
After the feast at Herot, Grendel attacks the warriors in the hall at night, killing many of them. This cycle of attack and retaliation continues until Beowulf arrives to defeat Grendel.
