This means that there are light and dark, astral and umbral "elements" as well. Was this given any significance later in the story?
As I recall, it is mentioned by either Minfilia or Urianger, that these dark crystals are how the Ascians can manifest themselves in a host body.
As for the Astral and Umbral elements, they are sort of like umbrellas, in that they each cover a number of the elements. Like the THM/BLM's Astral Fire and Umbral Ice, unfortunately I can't recall which of the other elements belongs under which umbrella.
