Write a short bedtime story about a dragon who is afraid of the dark.

Here's a short bedtime story:


Ember's Little Light

Ember was the smallest dragon in the Cinderpeak Mountains, with shimmering copper scales and wings like autumn leaves. But Ember had a secret that no dragon would ever dare admit.

Ember was afraid of the dark.

Every night, when the other dragons curled up in their cool, dark caves, Ember would lie awake, watching shadows creep across the stone walls. The darkness felt heavy, like it was sitting on his chest.

"Dragons breathe fire," Ember whispered to himself. "I shouldn't be scared of anything."

But he was.

One night, his grandmother Cinder noticed him shivering at the cave entrance, staring at the moonless sky.

"Come here, little coal," she said softly.

"I'm scared of the dark," Ember admitted, hanging his head. "I know it's silly."

Grandmother Cinder smiled and tilted her head toward the sky. "Look carefully."

Ember looked. And slowly, he noticed them — thousands of tiny stars, scattered like sparks from a campfire.

"The sky breathes fire too," she said. "You are never truly in the dark."

Ember looked down at his own chest. Even there, a faint warm glow pulsed softly beneath his scales.

He curled up beside his grandmother and, for the first time, slept peacefully through the night.


Sweet dreams. 🐉
