Grendel was mad because the party at the mead-hall (herot) was keeping him up all night so he kills the people. "Snatched up thirty men, smashed them...". "As day after day the music rang loud in the hall".
Beowulf comes in and takes off grendel's arm. Mankinds-enemy. "If he wins and death takes me". "My hands alone shall fight for me".
Grendel's mothr finds out that beowolf takes her son's arm so she drags beowulf into the monster's lair. Wolf-Den. "You will be rewarded for the battle you win". "Our only help, Again lies with you".
Beowulf kills Grendel's mother with his sword. "caught her in the neck and cut it through...". The witch of water. "Beowolf once freed proceeded to fight grendels mother but fate had decided that no mortal powers could defeat her".
Beowulf sword = Hrunting
Beowulf was ingjured by the dragon and one of his followers named wiglaf finishes off the dragon. Streaming current of fire. "The monster came quickly toward him, pouring out hot fire and smoke, hurling to his fate". "The beowulf rose, still brave, still strong.."
Beowulf died in the battle with the dragons so the geats built a tower for him. "Then the geats built the tower". Deserving of praise. "Of their dead king and his greatness, his glory..".
