Metallic rare Earth amalgam that when compounded in the presence of the Ætherine Cavorigen takes on the ability to completely block the force of planetary gravity. The inventor of cavorite, Dr. Cavor, had no Concept of the properties of ætherines but using his cavorite formula was able to build an anti-gravitational craft that he piloted to the moon in the mid 1800s. Presently the amalgam is used in many anti-gravitational applications. Unfortunately cavorite has awkward effects in that the motive force cannot be easily used in proximity with other forms of ætheric energy. The use of cavorite is also easily detectable making it unfavorable for military use.
