"Must I explain?"
"What have you done?"
"The lack of mana in the air must be constraining since a demon needs the constant flow to keep possessing the psyche of a tenuous lady."
"Pointless drivel," it laughed, swapping her voice for a deeper cruder cackle, "-you've won at what, taking away the mana won't do much. The painting, I'll kill and activat-"
"Enough," he thundered, "-look around, foolish demon, the very fabric of this room has been altered. Meanwhile we speak, everyone gets to live and enjoy the soiree. I would be impressed if the expansion was done subtly."
"My realm, tis negated…" it glared forward, "-what are you scheming?"
"Scheming, I say schemed, the latter's completed. The little mystery's been solved, and the prison released."
"Whatever you say," it smirked, "-I still have this body as a hostage; her memories speak of a fond relation. What would a dagger to her heart do, I wonder?"
