Resonance and Crystal Yesod

Discovered by the Lynks in their homeland Atziluth, this is a pearl-like crystal that grows in giant clam. The crystal makes a resonance like [radio wave], that can be manipulated, if constructed properly. Lynks alchemy tradition has developed from using this as [magic] to become the scientific word [technology]. Somehow, it is between such ideas. Especially this resonance field is used for [Reinforce] style of construction, like Tiferet Armor, or for airship and Ie=ga device.

Because it was harvested from giant clams, it is thought that some native animal species may have this kind of Resonance field or even to manipulate like magic, but Resonance is directly tied to the crystalline structure Yesod is only known use.

The Lynks have adapted this crystal structure to use in many of their technology. It's use is very bizarre and such a complex Lynks device, that often to just be thought of as [Lynks Magic], and so it is thought that Lynks are skilled at such an object [enchantment]. It is the manipulating of such a Resonance Field, that the [Ie=ga] can function, to store items in such a [pocket dimension]. On large size, it is used to store food and supply in the airship fleet, and the resonant fields can generate power. Many uses have been found by the Lynks for this, but after their homeland was destroyed, Yesod has become very difficult to find.
