The Scorching
The Scorching was a major event approximately 5,000 years before the present day. The event specifically was cause by a scavenger named Cottonmouth, by stealing a dragon egg. This action led to the dragon becoming the first dragon queen and leading an entire tribe to scorch all of Pyrrhia, slaughtering thousands of scavengers. The scorching is why present day Pyrrhia is majorly inhabited by dragons and not scavengers.
