The small boy jumped into bed clutching a stuffed gold dragon he'd gotten that day. It was his seventh birthday, and it had been the best yet. His family was short of money but it hadn't stopped his mother baking him a massive cake or his brothers (he had five) all saving up to buy him a miniature broomstick. Smiling contentedly, he snuggled beneath the pillows and promptly fell asleep…
"Aaahhh! Help! The dragon's gonna eat me!" He heard a voice scream from the marshes outside his house. Leaping out of bed he ran downstairs and out the door, grabbing his father's wand from the kitchen table as he passed. Following the source of the noise into the marsh, he soon saw a burst of green flame up ahead and he heard a scream he recognized as his elder brother's. As he burst into the clearing the wand lit up on his own, illuminating a huge emerald dragon with his brother pinned beneath its claws. He pointed the wand at the dragon's eye and shouted the only spell he knew.
"STUPEFY!" The beam of scarlet light erupted from the tip of the wand and travelled in slow motion towards the dragon's eye. When it finally struck its target the entire dragon flashed red and was thrown violently into the air. It landed on a wet, squashy knoll a few yards away. His brother scrambled to his feet and hugged him.
"You killed it! Thank you! How did you do it?" his brother gushed.
"It's not dead, just knocked out. I borrowed Dad's wand. It wasn't much, really," he said bashfully. "Come on, we should get back to bed." They trudged back to the house and back to bed, but not before he had returned his father's wand to the table. He fell asleep as soon as his head hit the pillow.
The small boy yawned and stretched, squinting at the sun shining through the thin curtains. Running downstairs he found his mother pottering about the kitchen making breakfast. "Mummy, guess what?" he said excitedly. His mother hummed her reply so he continued. "I know what I want to do when I'm older!"
She turned to face him. "Oh, really? And what would that be, then?"
"When I grow up I'm going to save people from big nasty dragons and put them back where they belong so nobody gets scared!" he shouted.
Smiling, she ruffled his shock of ginger hair. "That sounds like a good job, Charlie. You should do that."
And that is exactly what he did.
