"Come on, we have to get this before they come back. Scythe, quit messing with the fish!" said a large, red, mean-looking dragon, sharp fangs protruding from his snout. He hauled a huge, lumpy bag over his shoulders, gesturing to his comrades, Scythe and Blunt.
"Boss, I don't see the scalin stone in here..." Blunt said, eyes darting back and forth.
"Don't call me boss!" the green dragon snapped. "Call me..." he thought a moment, then said, "Call me All Powerful Jest. Yeah, that works." Blunt opened his jaws to reply, but he was interrupted by a huge, black dragon with jagged bat-like wings. She snatched Blunt in her jaws, snapping his spine like a pencil.
"Blunt! No, my brother!" Jest yelled in grief. Then he forgot, as a twinkling stone hung around the black dragon's neck caught his eye. "Scythe, cover me!" Jest commanded. Scythe nodded, then bared his fangs and blew a waving heat of flame at the black dragon. The black dragon roared in agony, and glared. Jest leaped, spread his wings, and grabbed the stone in his talons. "Scythe, let's go!" Jest said, then he grabbed Scythe's tail in his jaws, and zipped away.
"Get back here, runts!" the black dragon roared in fury. They made it, barely.
Back in their lair, Scythe and Jest peered over the shimmering stone.
"We did it," Jest breathed. Then, the stone started to crack.
"Um...Boss? I mean, All Powerful Jest?" Scythe asked nervously, "The stone is breaking..."
"It is not a stone! It's an egg!" Jest snapped, flicking his tail. They watched under the cover of night. The egg opened and a beam of moonlight hit a small, shiny red dragon with bright emerald eyes. She looked as if she had diamonds embedded in her back, wings, and tail. She looked up at the two full grown dragons and unfurled her tiny red wings.
"Precious. We call you Precious." Jest said, and knew that for the first time in his life, compassion showed in his dragon heart.
