I am in the process of changing all occurrences of the word "Subspecies" to "Manifestation" to better convey the traits' purpose.

Manifestations can be changed using potions, and determine special parts of a character's appearance, as well as potentially allowing for specific elements for the character.  Additionally, Manifestations are grouped into themes, and Manifestations of the same theme are similar.  Themes will be implemented as Subtypes.
