Gardinium

Gardinium is a silica based crystalline material, that forms on the asteroids within the wormhole accessible star system. It's main elements are silica, water ice and trace amounts of ferromagnetic compounds. It can't be replicated outside the system, leading scientists to agree that the special properties of the local star is key to the formation of the Gardinium crystals.

Material has several uses. It can be hard pressed into the crystalline plate form, and can be augmented by ravinium to form even tighter crystalline structure in the form of dense crystalline plate. The crystals can be used in a form of fusion reaction that consumes them and outputs substantial amounts of energy.
