Black magicite is responsible for many tragedies throughout Vana'diel's history. Black magicite is an extremely dangerous substance, possessing power beyond even ordinary magicite the source of the black magicite's power causes any person who comes in contact with it, or attempts to use it as a weapon, to become corrupted with darkness. "Black magicite" is forged from the crystallization of pure Emptiness. Energy surging through the line seeps out of the broken conduit and is absorbed by the cavern's soil and water, crystallizing into magicite. The primary theory behind magicite formation involves the broken conduits, parts of the ancient Crystal Line, which run through the caverns. Magicite is rare, having only been found in caverns under the well-guarded strongholds of the three major beastmen races. Magicite is an unusual crystalline substance of tremendous power. Three types of magicite (blue, green, and red) must be collected so that one of them may create the Destroy spell, which can be later obtained by fighting Deumion. In the Destruction floor of the Arcane Labyrinth, the mages mention magicite.
