Lucid

Lucid is a material type available in , Kingdom Hearts II, and Kingdom Hearts III. Lucid materials contain the essence of emptiness and are associated with Gravity and Aero magic.

Design
Lucid materials have an Elemental material structure and are clear.

The word "lucid" means "clear" or "transparent", hence their transparency. This is also reflective of the "essence of emptiness" that the materials contain.
