check over this paragraph for me.
The year was 400 AD, the year dragons plagued the lands. Some say they were a curse sent by an all powerful demon, others say they've been here since the dawn of time, waiting to take their rightful spot above everything. A powerful wizard named Harold found a solution to the dragons, he called in the slayer gauntlet, once you wear it you automatically become a dragon slayer and your duty is to fight off the dragons at all cost. Harold also created domes that would protect certain areas from dragons and allow life to progress on. Years later the great Harold would go missing but his work never ceased, because from his disappearance the dragon slayer guild was born. This guild trains willing recruits in the art of killing dragons and giving them the edge over existence. It's been 200 years and the war between humans and dragons still rages on. No one knows who the victor might be, but others know this war must end soon.
