Aerolites

Not all materials have a worldly origin.  Aerolites are a peculiar
type of material that has extra-dimesnional, planar, or spacial
origins and unique powers from this origin.  Aerolites are very
rare, and also very powerful, as they let a talented crafter combine
two or more materials into one to make a new type of alloy, gem, or
other material to work with.

Many unique recipies require aerolites, and they can be utilized to 
improve on an item before it is crafted.  After an item is crafted,
aerolites cannot be added - they may only be used durring the
creation process.  Listed below is a very small progression of
aerolites- there are definetly more out there.  Unlike the other
progessions, these are just ordered in rarity.  Each Aerolite has a
unique set of properties and conditions that must be met before it is
used.
