"I appreciate your making it clear."
"It's part of the job. So what'll it be?"
I raised my hands and the lines of force twisted like knives at each fingertip. Frakir dangled from my wrist and began to swing in an elaborate pattern.
Scrof smiled. "I not only eat sorcerers, I eat their magic, too. Only a being torn from the primal Chaos can make that claim. So come ahead, if you think you can face that."
"Chaos, eh? Torn from the primal Chaos?"
"Yep. There's not much can stand against it."
"Except maybe a Lord of Chaos", I replied, as I shifted my awareness to various points within my body. Rough work. The faster you do it the more painful it is.
Again, the rattling of the tin sheet.
"You know what the odds are against a Chaos Lord coming this far to go two out of three with a Dweller?" Scrof said.
My arms began to lengthen and I felt my shirt tear across my back as I leaned forward. The bones in my face shifted about and my chest expanded and expanded...
"One out of one should be enough", I replied, when the transformation was complete.
"Shit", Scrof said as I crossed the line.
