The historian Jezbar Foolion wrote a history of Duncanthrax's ascent to power called "The New Year's Revolt" sometime between 740~896 GUE. When writing this book, Foolion interviewed some of the last surviving eyewitnesses of the Flathead Revolution, some eighty years after the events in question. Nearly all of the dozen narratives relayed by Foolion contradict each other in the crucial details indicates that the last day of 659 must have been one of great confusion on the part of all involved.
