Natural Structure: Naturals structures are the form type containing the most variety: it includes any sort of inorganic, naturally occurring physical pattern, from the elemental structure of a mineral to the regular cycle of the seasons to stellar arrangements. Most of these structures are studied under the rubric of physics. Other commonly relevant discplines include alchemy, cosmology, and mineral lore.

Process to Actualize Form

think about the lattice within <gem or other crystal> as a seed for crystallization within <target>

The lattice structure of crystals is the basis for all true solids. Objects without such lattice are either not objects at all, existing more as a transient liquid or gaseous mass, or better thought of as slow-moving liquids. Further, crystalline structure, while inorganic, can to some extent maintain itself (and is sometimes thought to be at the root of or closely related to organic structure for this reason). An adept minerologist or jeweler can take the bits of a crystal as a basis for generating a much larger one. This form uses this physical process as a basis for a magickal one. One takes an existent lattice as a seed and refines it into a raw order or structure that is fungible enough to integrate with and permanently enchant another object. The object containing the original crystalline structure is destroyed by this process.
