This may or may not make it into the story, but it's interesting to see what the muses are giving me instead of the actual story.
Sora, Riku and Kairi were on a campout over the summer. They had brought their sleeping bags, tents, clothes and food, but all three had forgotten matches. It was now near dark and they were staring at the wood pile glumly.
Sora had been sitting with his hands in front of him on his legs when he looked down at them. A slightly puzzled expression came over his features as he tries to remember what was so important about them. He looks between the fire and his hand, with the same look still on his face. Sora slowly raises his hand so that the palm points towards the woodpile and says, "Fire."
To all of their shock a ball of flame shoots out of his hand and nearly incinerates the pile of wood they had gathered. Kairi quickly adds a few more pieces so that the blaze would last longer, and then both Riku and herself turn towards their boyfriend.
"What the hell was that?!" They all yell in unison.
"What'ya mean you don't know what you did Sora?!"
"I wasn't even sure what I was doing, Kairi!... However... Now that I've done it... I think there are others in there. Like other spells...? Or magick? Something."
