Beowulf

First it talks about evil and good, the difference between heaven and hell, specially how evil came to the world and where is it after everything happened. Then in a great kingdom there's a warrior who with his army will fight against a monster, and they're planning the attack, and saying that if destiny says is time for them to die, then is time, but a great warrior from outside came to and he will help them to win the battle. Defeating the monster was difficult because he kind of like enchanted the warrior's weapons so they can't hurt him, but at the end they won the battle and the monster was death. The next fight was against a witch and the third against a dragon, these warrior won all of them so everyone celebrated his victories
