You lived in a village of Vikings, unfortunately dragons are a big issue for survival. Dragon attacks were more frequent that rain storms, either destroying buildings, eating crops or live stocks.
There was this one dragon that would come frequently, always terrorising the village. Other Vikings tried to kill it, but it was proven to be a huge problem. Until during on of his attacks, the village was under lock down. Vikings prepared there weapons for attack, and by luck shot a spear to its wings. The dragon retreated back in the air until one of the Vikings shot a net at him, taking advantage of his weakened state. The dragon soon collapsed in the distance.
You were tasked in retrieving some berries from the forest, you walked along the path until you heard some growling in the distance. You diverged from the path and found the dragon, it's body entangled in the net and an arrow in it's wing. It's eyes snapped towards you, growling as it got into a defensive stance ready to attack when needed.
