Returning a sly smile edged with anger to the Tiefling, you give the man in the center of the room the best glare you can muster, before breaking out into an open laugh.

"Uptown Whore? My, you really have no idea, do you?"

Your voice is husky and measured, with consideration and an edge of menace behind every word.

"My dear friend, with only a whim I could incinerate this entire building, without so much as singeing my skirt."

You confidently stride into the room without a care for the weapons around you, closing the distance between you and the leader with every word.

"Or perhaps, something more subtle would be appropriate. How would you like to turn yourself in to the city watch? Minds are such simple things to toy with, after all..."

Finishing your walk within arms reach of the man, who stares at you with incredulity, you delicately place one of your gloved hands on his cheeks. He doesn't move to stop you, while you lean in close and whisper into his ear. Even the tiefling woman seems nonplussed by your speech, though she recovers before anybody else notices.

"Or maybe, you leave my friend alone, and your men walk away with their lives. I'd be very appreciative."
