I have faulty memory, and I said this on a previous chapter, but what should happen is...
The ancient dragon is acting as chaperone (older brother) for two young dragons, one of which wanted to "play" with humans in the form of pretending to be a big shot, and forcing them to declare war. Long story short, the kids turn into ground meat, and the chaperone flees and becomes a sobbing mess. But yeah. Left a bad taste in my mouth.
