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.

The year was 400 AD, a time when dragons plagued the lands. There were differing beliefs about the origin of these creatures. Some believed they were a curse sent by an all-powerful demon, while others thought they had existed since the beginning of time, waiting to claim their rightful dominance over everything.

Enter Harold, a powerful wizard who discovered a solution to the dragon problem. He devised the slayer gauntlet, a powerful tool that, once worn, bestowed upon the wearer the abilities of a dragon slayer. Those who donned the gauntlet had the duty to fight against the dragons at any cost. Additionally, Harold created protective domes, which shielded specific areas from dragon attacks, allowing life to continue unharmed within them.

Years passed, and although the great Harold himself went missing, his work continued. From his disappearance arose the dragon slayer guild. This guild was established to train willing recruits in the art of killing dragons and to equip them with the necessary knowledge and skills to triumph over these creatures.

Over two centuries have elapsed since the guild's establishment, and the conflict between humans and dragons still persists. The outcome of this war remains unknown, but some are aware that it is imperative for the conflict to be resolved in the near future.
