The Ghosts of Razgriz

“But what the dragons in general hadn’t realized was that, in the absence of physical predators, time itself becomes a predator. Dragons got accustomed to being top dogs. They started to enjoy the whole shock-and-awe thing. They forgot that humans weren’t just dumb sheep with thumbs.

First the dragons grew complacent; then they got lazy. And the universe cannot suffer laziness because it leads to species-killing mistakes. The dragons’ mistake was when they started keeping familiars, because before you knew it, the humans had moved on up from carrying logs and shoveling dragon shit to bringing home the bacon.
Next thing, those familiars were doing the books and giving pedicures, making themselves indispensable, making themselves invisible. Dragons allowed those humans to build quarters for themselves inside the walls. Dragons blabbed on about politics and strategy while their familiars were in the room. And goddamn if those familiars weren’t taking notes.
It didn’t take more than five hundred years and half a dozen failed revolutions before those smart little humans were running the show, and any dragons who had survived the purge were reduced to hiring themselves out as muscle or skulking around in various inhospitable shitholes.

And still humans ran the show, keeping themselves sharp by becoming their own predators, which was twisted as hell.”
