Due to having access to YouTube, I've seen the Best Ending for Demon King Domination. It would be interesting to see if that little tidbit at the end (not stated here to avoid spoilers, but Changer knows which one, I'm sure) ended up tying into Heidal's presence in the Elf Kingdom, and why it was so easy for a weak Human to usurp the Throne. Heidal's policies made the Elves mostly horny sluts, and they no longer practiced combat in Coliseums, which is a great place to gain combat experience outside of war. This would also probably be a good subplot for Dianne, (if the player has summoned her by that point) because [spoiler alert] her kingdom was destroyed by the same entity, and she wants revenge.
