Renadeus looked at the blast with disgust. He slowly began to heat, simmer, burn with rage. His eyes glowed a bright red, and his skin contorted unnaturally. He slowly turned back to look at Twilight, who was still cowering in the corner, covered with burns. A small smile twisted its way onto his face of rage.

"Prophet. Go on and greet our guests nicely," he said. The lights in the room dimmed, before cutting out completely. "And give them my regards." He stomped his hoof against the ground, producing another red crystal. This one was unusually dull, and was shaped almost perfectly spherical. "When you reach them," he said in hushed tones, "touch this against their skin. Then, only then, will you be safe from their lies."

Twilight shook her head. "I won't do it. I won't." She looked at Renadeus with a look of almost hatred. "You can force me into a cage, you can shock me and poke me and beat me, but I'll never fall to your level. I'll never kill another pony."

Renadeus laughed. It was a long, hearty, chastising laugh, and his head rolled back as his chest heaved. "Oh, young Prophet. You truly are naive, aren't you?" He suddenly stopped laughing and looked her in the eye. "You will do what I ask of you. They will not die, I promise you that. But if you do not do this, then they certainly will." He generated another crystal. This one was sharpened to an impossibly fine point, and seemed to be perfectly shaped for penetrating into things. It was bright red, and positively radiated with energy. He picked it up in his hoof, a slight tingling sensation manifesting as he did so.

"I would hate to do that, you know," Renadeus said as he held the sharp crystal, occasionally switching it from hoof to hoof. He stamped his free hoof against the ground. "Don't make me do things I hate. Now, Prophet. Their fate rests with you, you know."

The door to the cage opened, and the lights came back on.
