grendels mother goes to heorot to avenge her sons death
Beowulf followed Grendel's mother's tracks to her underwater lair after she attacked Heorot. He dove into the lake and ultimately battled and killed her with the help of a magical sword he found in her lair.
Fighting Grendel, Grendels mother and the dragon once he returns home to Geatland and is crowned king.
The dragon is beowulfs song which most people don't' know cause it doesn't really tell you... and the golden horn Beowulf got from the king is a symbol. If Grendels mother has it he shall not attach but it soon comes back to it's owner and it comes back to Beowulf when he becomes king. So Beowulf and Grendels mother got to gather and he gave her another son, he just couldn't help it. so Beowulf really doesn't kill Grendels mother he just says he does.....
Beowulf and Grendel's mother fought in her underwater lair at the bottom of a dark, eerie mere (a kind of lake). The battle took place in the depths of the water, adding to the suspense and danger of the encounter.
