Joko slew Abaddon. Joko slew Zhaitan. Joko slew Mordremoth (how did Elonians even know!?). Elonians praised Joko, believed him to be some god-king. He lied to the masses with propaganda, proclaiming he was the savior of their past plights. Heck, Joko even slew the Iron Forgeman of Sorrow's Furnace according to his propaganda. I know both were overtaken by tyrannical individuals capable of manipulating history to fit their fiction, but while Joko lived to modern times, Usoku didn't. It would be a bit boring to just repeat the same old plot in different aesthetics. Less that and more The elder dragons are a myth. You are are safe from in Cantha. More the ministry is in control of the emporer. I can see the ministry go to any means to keep the people of Cantha complacent in that notion.
