Dilythium coal is a naturaly occuring mineral consisting of elemental compounds compiled in a intricate crystaline structure. The mineral appears black peppered with glittering specks throughout. The generation of the cystaline structure requires the absorbtion of energy over exceedingly long periods of time. Dilythium therefore contains an exceptionally high potentail energy. This energy is released within the dilythium Furnace of an Ætherdrive by breaking down the crystals bonds by exposing the mineral to mixes of ætherines. The excinertive reaction converts all matter to energy and produces an energy field to allow additional energy to be drawn through from the sub-æther leaving only the raw Ætherine residuum and ætheric distilate as by-products.
