The Boy Who Played Worm

Don't be mean to your sister, or a bore worm will scoop you up!
You don't know about the bore worms? Well, let me tell you...

Years and years ago, when the realms and gods were young, it is said a young kid was skipping through the plains. He saw there were holes in the plains, but he wasn't afraid, because he knew he could simply walk around them. And so the boy trotted around the holes, peering down into them curiously. He saw a strange thing in the hole, but he was sure what it was, so the boy went and got his sister. He brought her to the hole, and made her look into it.
"Look!" he said. "Do you see the worm?"
When she was leaning forward to look, the boy pushed her on the back, and down in the hole she went! She tumbled and tumbled, and when she landed the boy couldn't see her, because she had fallen into the darkness of the hole. Soon, the boy began to panic when the girl did not appear, and did not answer when he called out to her. He ran home to his parents, and when they saw his crying and panicked face, they knew something was amiss. But he would not tell. His parents pressed him and plied him, but he would not budge.
Eventually, when the sister did not return, the parents grew furious with the boy.
"How dare you not tell us when you know what has happened to her!" they said.
They took the boy and carried him to the hole, where they threw him in and he fell and fell and fell and landed straight in the mouth of a hungry bore worm that had been sleeping in the hole. He immediately screamed out, and the worm woke up and ate him, rising from the hole as it did so. The sister, who had wisely kept silent, rode the worm up and out of the hole. She was reunited with her parents, and the worm left to find a better hole.
