Suspendium

Suspendium is a miraculous mineral. The higher the purity of Suspendium, the better it floats in areas of high Shinsoo concentration. Pockets, Inventories and Lighthouses are all made from suspendium(Ch 40).

Light Bearers must manipulate Shinsoo, so their Lighthouse can float, as a Lighthouse is made from minimal purity of Suspendium.
