Much in the tradition of your favorite "Let's destroy all evidence of the past in order to reshape it as we see fit" storybook, King Harandraff the Great enacted what he liked to call the Absolute Erasure to do just that. That is, to destroy all evidence of the past in order to reshape it as he saw fit.
While sitting in his grand throne, having just beheaded his top advisor, the idea struck him like so many Aelfants charging: He would simply rewrite his journals and his castle's rosters to exclude any mention of him ever having a "top" advisor. And thus it began, with him executing one of his staff, and tasking the remaining servants to erase him from existence. Soon it became an addiction, and the great King of all Ghyll began stretching his reach outside his castle.
In one instance, he removed the drawbridge in front of his castle and replaced it with a canopy to shade the creatures of his moat. And the very next day, nobody who had previously knew about the drawbridge knew about it anymore, or else they were beheaded. And anyone who knew those certain behedees was also told to not know about them, lest they find themselves headless also. Needless to say, Harandraff had a remarkable number of people killed in order to prevent anyone from knowing that they were killed.
It was around the first days of year -397 EC that Harandraff's plan began spiraling out of control. Bute University, having been founded three years earlier, was becoming ever more of a threat to the King's hobby of rewriting history. By this time, the King had written his family to be the wealthiest, most prominent, strongest, smartest, and overall the superlative family of Ghyll proper. Knowing that this was not true, and jumping at the chance to provoke the King, Bute published a family tree outing the King's brethren as slovenly drunkards, as rightfully they were. So the King infamously appointed Exis Ehnos to head an Army that would march to Bute and give them "a stern talking-to and numerous slaps on their wrists."
