The Five Dragon Killers

There are five magic items that were crafted for the purpose of hunting and killing Dragons of the color of the weapon.   Crafted by the Elf and the The Clan of Iron to try and counter the Dragon invasion.   The dragon wars finally ended when Five weapons were created. Each one specific to a type of dragon. After killing many dragons and leveling the playing field the dragons and the people came to a agreement. The dragons would find leave the people alone. Stop attacking cities and crops. They would stay in their own territory and people would stay out. IF The weapons were each sealed in a tomb with a curse on it. If the tomb is ever opened the dragons of that type would know and the agreement void.   The agreement was sealed over the bloodstone where the oldest dragons of each type and the leaders of the planet swore a blood oath and came to an accord.   Ending the Dragon wars and bringing an uneasy peace that has lasted many generations.   In some places people have not seen a dragon in so long they wonder if they still exist. But fear keep most people away from places that are considered dragon territory.
