the wolf's sword

Here is the Wolf's sword, inspired by my own concept.
A sword forged in the blood of the battlefield companion.
One day, a young squire encountered a lone wolf feeding on corpses on the battlefield.
The young knight was searching for a royal relic lost in battle. Instead of chasing the wolf away, the squire offered it his ration of bacon. Fearful, the wolf hesitated to take it. Then he grabbed it and fled into the forest. When the squire took part in other wars, he saw a familiar figure appear at the end of each battle, as if he brought good luck to the young man and his clan.
But during one battle, enemies launched an impressive number of arrows at their clan and the surrounding area, so many that the sky was no longer visible. The squire's clan was forced to retreat. Worried about the situation, decided to return to the battlefield to see if his friend would come back. Taking a huge risk, the young man returned late in the evening to enemy territory and saw his friend riddled with arrows. Totally devastated by this sight, the apprentice knight decided to recover his friend's body and forge a sword in honor of his dead friend. Soldiers say that the gem in the center of the wolf's head on the sword contains his friend's blood, and some say that on the battlefield, the knight never lost another battle and that sometimes an animal rage animates the young knight, making him invincible and unstoppable in this state.
