" There were dragons when I was a boy. Ah, there were great, grim sky dragons that nested on the clifftops like gigantic, scary birds. Little, brown, scuttly dragons that hunted down the mice and rats in well-organized packs. Preposterously huge sea dragons that were twenty times as big as the big blue whale. Some say they crawled back into the sea, leaving not a bone nor a fang for men to remember them by. Others say they were nothing but folktales to begin with. I’m okay with that.
Legend says that when the ground quakes, or lava spews from the earth, it’s the dragons, letting us know they’re still here, waiting for us to figure out how to get along. Yes, the world believes the dragons are gone, if they ever existed at all. But we Berkians, we know otherwise. And we’ll guard this secret until the time comes when dragons can return in peace. "
