Anti-Gravity Crystals

Ettrlurium Crystal is a strange crystal stone found in abundance in the deepest caves and mines of Gradus 9z. This material is mysterious, when an electric current is connected directly to a small Ettrlurium stone, the stone levitates and is suspended in the air, the larger the stone or the greater the amount of energy is, higher the stone will be.

This crystal is used in small and large anti-gravity engines for airships and flying vehicles of The Batonn Empire, it also works in space on atmosphereless planets, is used in ettrlutium cannons, energy cannons that fire a high-speed electric shot, and in the famous Rifle Atrax, a rifle invented by the great scientist Doctor Atrax that casts a beam of light that can levitate the heaviest of objects.
