Oz

Ozmium (OZ) ['äz'mēəm] combines Oz- (an ideal or fantastical place) with -mium (like an element) to call to mind ideal and fantastical elements powered by a tangible expression of real human belief, a weight of which we call the units "onz[es]" and notate them as oz. (e.g., one-hundred Ozmium is 100oz.)
