“if the greens could reproduce, considering their amorousness and the numbers we have of them, we’d be up to our ears in dragons in next to no time.”
This is another thing about the world-building that bothers me. Only golden queen dragons are ridden by women, all other dragonriders are men. I could maybe hand-wave this away if dragons prefer a rider that matches their own sex, but that's clearly not the case since all female greens have male riders.
