Far behind her, the large, orangey colored egg lay in a narrow, dim corner of the cave where it had lain for centuries. It was partially covered with rock dust and dried bat guano. The splattered brown spots on its outer layer looked like something had splashed and run down its sides, then dried on it, although the spots were part of its unusual color. Between the splashy brown, the orange of the egg seemed to slightly glow in the low light that filtered into the cave from the small opening hundreds of yards away, where the Oracle sat cross-legged on the ground keeping guard and waiting.
Over time, the egg had many visitors, yet no one or nothing had really noticed it was even there. The deep cave was warm and dry, and small bears, snakes, rats and of course bats came and went. Lizards died on top of it, shriveling into dust. Insects crawled over and around the egg, never disturbing it. Once, before the Oracle had arrived to her assigned place, a group of humans dressed in spelunking gear and carrying bright lights had passed it without noticing that it was more than a rock tucked away in a dark corner among other large rocks and small pebbles. And so, alone in its dusty nest, it incubated.
It's storming hard, and I had nothing else to do except dream up this quirky little flash fiction, but I can't seem to bring it to a quick close.
All it needs is one quick paragraph to finish it.
