Frostwing was mostly just keeping his tongue for now. He was not familiar with how elves acted, but he did know they were powerful. He kept his head down and did not make too much contact.

Suddenly the imp would have forebode you will get when someone, or something, evil beyond compare is watching you. If he had the guts to look up, he would see a Bone Claw, the assassains of the undead world, and masters of their trade. Fast, strong, and skilled in stealth to the point they almost blend with shadows, these are forces to reckon with. It climbs down, and grips the imp with a unclawed hand, and says "shhhhhhhhhhh, it'ssssss okayyyyyy. This is just for my own pleasurrrrrrre." He puts the tips of his other hand on the imp's back. And lets his claws out.
