lightning circuit

“Okay, Randy. I’m only going to do this once.”
I dropped my staff on the ground, held up my hands in front of me, palms facing each other, drew in a whisper of will, and murmured, “Eggus Chennus.”
Green-gold lightning, not a ton of it, exploded from my palms, forming a current of energy that snapped and crackled in the sultry summer air, contained within the space between my hands.
I had thought through the spell before, but I’d never really tried it. It worked pretty well—except that rather than just going away, the power was cycling up one arm, around my shoulders, down the other arm, and then out between my hands again. It was a cycle that fed upon itself, and between that and the power-laden air of the terrified city, the energy built a whole hell of a lot faster than I would have liked. It had to go somewhere.
I picked a tree and unleashed a stroke of green lightning that smashed into the trunk about five feet up and brought the tree crashing down. It started burning with green flame, green flame—all hell was breaking loose. I could only attribute that to the breakdown in reality that Bob had warned me about.
My volunteers had fallen silent.
Randy looked like he’d swallowed multiple bugs.
“Wizard,” I reiterated. “Any questions?”
