Wind carved from air?  Well...<br/><br/>"First thoughts?  Wind-eroded stone, so an area with a LOT of heavy winds.  A large deposit of blue jade may fit, especially sculpted from it, or something carved and visible from an aerial view.  Possibly something hit by a lot of lightning too, that split or glassed it." she said, just tossing out ideas as they came to mind "Alternatively, it could be a reference to terrestrial-level sorcery, couldn't it?  Or to something else associated with Caste abilities for the Air aspected?  Just ideas... you have any working from those?"
