Deconstructing the Demon Book

"Okay so let's talk about the Demon Book."  Simon talked and chewed on his pizza at the same time. 

"First, I'll tell you what it's NOT." 

He poked a finger into the pizza and pulled out a mushroom.  "Yuck I hate mushrooms."

He leveled a gaze at me.  "The Demon Book is NOT a cook book.  It doesn't give you directions and recipes on what to do to conjure up a demon and it doesn't tell you how to interact with a demon."

I grabbed the plate of finger sandwiches from the tray and ate a finger of cheese and roast beef.  It was dry and tasteless but I had to eat something to swallow down the pill. 

"That's all good and dandy but we're trying to figure out how to handle a demon-assisted weapon.  What's the use of this book if it has nothing to do with demons?"

"I didn't say it doesn't have anything to do with demons."
