A wide grin, sorely lacking in the front tooth department, splits the man's face. "Sure hope it ain't for Peace." He guffaws and drags you upstairs. He takes you by your broken hand. The pain will prevent you from using your left arm for two turns.
At the top of the stairs, the man presents his intricate machine to you with a dramatic flourish of his hands. "See that?" he asks. "That's my Awesometastic Doohickey 9000." With a shrug, he admits, "The name could use a bit of work, but the machine? She's a beast!"
He takes you to one end of the machine, where there are two ominous needles the size of your arm about ten feet above an uncomfortable-looking slab with leather restraints. The chamber of one of the giant needles is filled with a black liquid, too dark to see through. "All I gotta do is tie somebody down and flip a switch, and this machine will switch out the blood in his body and replace it with that motor oil. Make donating to the Red Cross a breeze." His guffaw comes out as a pained cough. "Though it don't turn out too great for the other guy."
Again, the man points his gun at your head. "If you want, I can give you an up close and personal demonstration. Take a seat." His persuasive tone implies that he simply will not take no for an answer.
Edit: Yikes, that was long... sorry!
