The boy stepped towards the creature. He'd lost his only weapon stopping his escape. Ordinarily, this would've been a tactical fallacy. But he now had access to his own personal armoury.
A dark mist emanated from the boy as he stepped towards the fallen creature. The boy raised his hand and the mist shot out tendrils towards the creature, grabbing at his leg and wrapping itself around his throat. The thing started hacking at them with his axe. The boy was not concerned. He turned his attention to a nearby house. More of the dark mist billowed out of him, reaching down the street, and with this extra mist he summoned up massive tendrils of darkness. He ripped off the front of the house, exposing the occupants inside, who had received a most rude awakening. The tendrils pierced their chests, and the boy sucked in their blood to his wrist, while putting his other hand out as if to catch something.
Whatever he had caught, he threw it to the floor and three almost incorporeal beings, approximately the height of children, appeared out of the ground, seemingly made of pure darkness. Their appearance was almost invisible, as only their heads stuck out of the mist, and they blended in perfectly with the blackness. After they finished emerging they immediately hunched over, making them completely undetectable. The boy spoke to them in a foreign language, and they ran off into the night, breaking into homes that were surrounded by the mist, and killing their occupants. Then the mist would bring the Blood back to the boy.
The darkness swirled around the boy, lifting him up ten, twenty feet into the air. From his living tower of mist, he watched and directed the massacre, leading masses of the strange black "children" to deal with the rallying militia, slaughtering them before they could gather and insuring that they did not become a threat. Whenever one of the militiamen hacked away a piece of one of the demons, it would dissolve back into darkness, go through the mist back to the boy, and be reborn by the boys magic. And with every kill he gained more.
But as the boy looked around, he noticed something...the creature, wounded leg and all, had fended off not only the mist, but also several waves of his minions. He gathered together two dozen of his minions around the creature, and as one the monsters attacked.
They leaped towards the fallen monster, eager to be the first to draw his blood, when suddenly they all dissolved. They did not go back into the mist, to be recreated by the boy, the monster who had started all of this. They simply dissipated into nothing.
And then a voice entered his head, like thoughts he might think, except he did not think them.
Can you see them, Claxtio? Can you see the remnant souls?
