Explanation:
In the epic poem after the fearless hero Beowulf successfully slays the monstrous creature Grendel in Heorot, the Danish mead hall, he embarks on a perilous quest to vanquish Grendel’s vengeful mother. Determined to avenge her son’s death, she resides in a treacherous underwater lair. Equipped with the mighty sword Hrunting, a gift from Unferth, Beowulf dives into the dark depths and confronts the formidable foe. The battle is fierce, with Grendel’s mother gaining the upper hand momentarily, but Beowulf eventually discovers a powerful, enchanted sword forged by giants on the wall of the lair. He seizes the weapon and delivers a fatal blow to the monster, ultimately defeating her and bringing an end to the malevolent threats that plagued Heorot.
