Mother's revenge

After I dealt with Grendel, he went home to his mother and bled to death. Grendel's mother, enraged by the death of his son, killed Hrothgar's best friend. The death of Hrothgar's friend caused him to go into depression and he needed Grendel's mother dead. He called on me once again to deal with her. This was much more dangerous than my battle with her son. I knew I had to go to her underwater lair, so I prepared myself with armor and weapons. On the way down through the underwater hell castle, I had to remind myself over and over to stay alert and be ready for anything. It was getting hotter every minute for hours. Swimming in this near-boiling water is harder than I ever imagined. Grendel's mother spotted me first and swam toward me. She grabbed me and sat on me with her enormous body. While immobilized, many creatures and monsters tried to end my life, but i was protected by my helmet and chain-mail. Grendel's mother also tried to stab me with a very rusty and bloody stained dagger. Her attempts were not enough to harm me greatly. In frustration her grabs me and take me to her battle room. This was a terrible decision because I was no longer fighting under extreme temperatures. As I strike her with my blade I notice that it isn't damaging her at all, but as soon as I begin to lose I see this large two-handed sword on the wall that was hand made by giants. I retrieved the sword and get close enough I split open her thoat and watch her die.
