What an oddly specific gift. In lifetimes past, in another land and with another face, he had often reordered the rooms in his castle with the flick of a wrist, one of the many unique facets and benefits granted to him by the curse privilege of being the Dark One.

The face this man presents to the world is his own; he simply does not ask that anyone interpret it.

"I believe a demonstration would be in order, yes." Ever courteous, ever polite, the warning receding just as easily as it came. "If it is not inconvenient. I believe your word, however, is all that is required."
