White Materia The White Materia is a powerful Materia in " Final Fantasy VII " and is counterpart to the Black Materia . Both are unique , there being only one of each . The White Materia is used to speak directly with the Planet and once the Planet receives the message , the Materia glows green . It is used to summon the " Ultimate White Magic " , Holy , which summons the full power of the Planet to protect the continuation and harmony of life . Story . Long ago , the Cetra were given two gifts from the Planet : the Black Materia , which had the power to destroy , and the White Materia , which had the power to protect . Being peaceful people , the Cetra embraced the power of the White Materia and rejected the Black , sealing it away by transforming it into a complex , booby - trapped , labyrinthine temple that became known as the Temple of the Ancients . When the extra - terrestrial organism , Jenova , fell to the Planet , the Cetran civilization was nearly wiped out before Jenova was sealed . As they had kept the knowledge of both Black and White Materia from their close cousins , the human s , the knowledge of Holy slowly died along with the Cetra as their numbers dwindled . Ifalna , the last remaining Cetra , lived in solitude in Icicle Inn to the far north , concealing the secret of the White Materia . When she died young she was forced to pass the Materia on to her daughter , Aeris Gainsborough , while the girl was still a child ignorant of its true power . When Aeris becomes involved with Cloud Strife and AVALANCHE in their fight to save the Planet , she becomes aware the White Materia ' s abilities and realizes that if Sephiroth plans to summon Meteor , the only way to stop him is to summon Holy . She leaves Cloud and his allies — knowing Cloud is under Sephiroth ' s control and can ' t be trusted , much as she wanted to believe in him — and heads north to the Forgotten City , where she begins to meditate to call upon Holy . As Aeris contacts the Planet , Jenova — in the form of Sephiroth — impales her through the torso with the Masamune , killing her . The White Materia , which Aeris had hidden within her hair , falls into the lake beneath the village . Although everyone at first believes reaching the Planet is now impossible with the last Cetra dead , they later learn Aeris ' s prayer had reached the Planet , but Sephiroth is preventing the spell from answering the call . To release Holy , Sephiroth must be defeated but by the time this happens Meteor has already entered the Planet ' s atmosphere , and it is too late for Holy alone to force the object back without also harming the Planet . Aeris ' s spirit summons the Lifestream to supplement Holy ' s power . Although the clash between the forces creates a magical storm that destroys Midgar , Meteor is repelled , and the Planet is saved . It is unknown what happened to the White Materia afterward , but it can be assumed the White Materia still lies in the bottom of the lake in the Forgotten City . Other appearances .
