Black Materia

The Black Materia is a materia utilized to cast Meteor, described as the "Ultimate Destructive Magic", in Final Fantasy VII. It is the opposite of the White Materia, the "Ultimate Defensive Magic", which summons Holy.

Much of the plot revolves around the pursuit of the Black Materia, both by the party (in order to safeguard it from those who would misuse it) and by Sephiroth (as a vehicle for his plans). The party is able to obtain the Black Materia at the Temple of the Ancients, but Sephiroth controls Cloud to relinquish it against his will, both there and later at the North Crater. With the Black Materia, Sephiroth casts Meteor, which is later destroyed in the ending by Aerith's spirit controlling Holy and the Lifestream to protect the Planet.
