Jynx snapped a hand out to keep him from stepping over the threshold, head tilted and eyes narrowed warily. "Wait," she murmured.
She could have checked the room herself--but hell, the guy already knew she was a demonlord, or should have at least guessed. May as well do this the easy way then.
Holding her hand out, she Summoned quietly, "Tiameth, come to me."
In a soft pop of inter-dimensional tension snapping and a puff of the scent of brimstone, the smallish, fox-like creature appeared in the air above her left shoulder, wings flapping quickly. Jynx nodded to the room and muttered, "Take a look, make sure we're alone."
The demon gave a quick bark of understanding and fluttering into the room, making her way around the perimeter.
