Dilithium

Crystalline substance used in warp propulsion systems to regulate the matter/antimatter reactions that provide the energy necessary for faster-than-light speed. Naturally occurring dilithium was extremely rare and was mined on only a few planets, such as Coridan,^[1] Troyius^[2] and Rura Penthe.^[4] In 2286, a method of recrystalizing dilithium was discovered, reducing the need for mining new deposits of the mineral.^[3]
