Jake the Dog and Finn the Human were racing to the Candy Kingdom. "C'mon, Jake! I'm gonna beat you this time around!"
"Not today!" Jake stretched his legs so that he passed by Finn in two long strides.
While running to catch up with long-legged Jake, Finn tripped on a large stone. At least, it looked like a stone. It was a dull purplish-grey in color, slightly bigger than a loaf of bread. It radiated heat. "Hey, come look at this thing."
When Jake turned around to see the thing, he felt the warmth emanating from it. His eyes widened in realization. "Finn, this might be one of those fire-stones that the old homeless guy from the Slime Kingdom told us about! 'He who knows how to use this stone can wield the power of infinite flames.'"
"Sweet! Let's try it out!" Finn picked up the stone - or, at least, he tried to. The stone was unbelievably heavy.
Jake attempted to pick up the stone, and succeeded in doing so. "So," he questioned, "what do we do now?"
"Hm." The twosome thought for a minute. Finn came up with an idea: "Maybe we should go ask PB. She knows a lot about science and stuff. Maybe she knows how these work?"
"Good idea. Get on!" The boy climbed onto Jake's back and ran off where they had intended to go to in the first place.
In the distance, a man hidden in the shadow of a nearby tree watched and laughed. "Fire-stone indeed. I can't wait to see the surprise on their faces when that 'stone' hatches. Then the Jerk will have another beast to uglify..." The man disappeared in a cloud of dust and sparkles.
A/N: Another super-short intro? Big story on the horizon... But probably not as popular among the masses as NSWL.
But we'll see how this does...
