channeling sells energy

And something about it, intangible, something I couldn't name, called to me. Beckoned. Here was power, power I had thrust aside once before, in the past. I had thrown away the only family I had ever known to turn away power exactly like this. This was the sort of strength that could reach out and change the world to my will, bend it and shape it to my desiring, could cut through all the petty trivialities of law and civilization and impose order where there was none, guarantee my security, my position, my future.
And what had been my reward for turning that power aside thus far? Suspicion and contempt from the very wizards I had acted to support and protect, condemnation from the White Council whose Law I had clung to when all the world had been laid at my feet.
I could kill the Shadowman, now, before he knew I was here. I could call down fury and flame on the house and kill everyone in it, not leave one stone upon another. I could reach out and embrace the dark energy he had gathered in this place, draw it in and use it for whatever I wanted, and the consequences be damned.
Why not kill him now? Violet light, visible to my Sight, throbbed and pulsed inside the windows, power being gathered and prepared and shaped. The Shadowman was inside, and he was gathering his might, preparing to unleash the spell that would kill me. What reason had I to let him go on breathing?
I clenched my fists in fury, and I could feel the air crackle with tension as I prepared to destroy the lake house, the Shadowman, and any of the pathetic underlings he had with him. With such power, I could cast my defiance at the Council itself, the gathering of white-bearded old fools without foresight, without imagination, without vision. The Council, and that pathetic watchdog, Morgan, had no idea of the true depths of my strength. The energy was all there, gleeful within my anger, ready to reach out and reduce to ashes all that I hated and feared.
The silver pentacle that had been my mother's burned cold on my chest, a sudden weight that made me gasp. I sagged forward a little, and lifted a hand. My fingers were so tightly crushed into fists that it hurt to try to open them. My hand shook, wavered, and began to fall again.
