Thousands and thousands ago the voidal plague was made by a group of mages seeking change in the world. Unfortunately the plague went out of control and went berserk. A mage (who wasn’t one of the mages that made the plague) would later on seal it away.However, the seal would start to break over time. Fast forward to the present the seal would end up breaking and take over the minds of the queen and king seeking revenge because the royal family actually started with that one mage. The king and queen which are under the effects of mind control then started to mass manufacture it since when it took over their minds it was in a weak state. The void key that gets dropped is the key that locks the Void Eater. A device that was made by scientists ages ago to contain and get rid of the plague. Unfortunately the scientists never knew the location of the seal so it was never used and was then hidden in the castle.(The plague was also sealed hidden in the castle just no one noticed lol) The only reason why the king queen never used it was because it was lost to time and that they never believed in their ancestry. Now you the player has heard and believed that the plague was real so you set out on a journey to finish what the mage couldn’t finish himself. Later on when you sneak into the castle because you’ve heard rumors about the king and queen not being themselves you end up finding the Void Eater and after you beat the king and queen you get the key and use it on the Void Eater and it gets rid the plague bringing peace to the land and now you are acknowledged as a hero yippeeee the end =D
