Banora Underground The Banora Underground is the final dungeon of " Crisis Core - Final Fantasy VII - " and a secret network of caves underneath the town of Banora . The caves are mazes of naturally made caverns and waterways , the ruins of Shinra Electric Power Company ' s laboratories and private prison facility , and an area with a statue of a woman holding the Goddess Materia . The Banora Underground is home to the most powerful enemies in the regular game of " Crisis Core - Final Fantasy VII - " and once the player enters they cannot leave save for missions . To unlock the door to the final battles , the player must find seven special Materia , called the Goddess Materia : Light Materia , Star Materia , Heaven Materia , Ground Materia , Life Materia , Sabbath Materia , and Being Materia , that are scattered throughout the dungeon . Story . The village of Banora was one of many sites examined by the Shinra Electric Power Company for the potential to host a Mako Reactor . The underground mines were built with this purpose in mind , with the village constructed to conceal the mines ' existence . The mining site was closed when Shinra discovered the Emerald Weapon in stasis , and the village was built to hide the discovery with Shinra staffing it with residents . The implication thus is that the Banora Underground leads to the caverns beneath the northern continent . Shinra employees were placed on the village board of trustees but eventually the company lost interest in the site and Banora became a free village . After the Jenova Project , Genesis Rhapsodos was sent to live in Banora under foster parents , as were Gillian Hewley and Angeal Hewley and others involved in Project G , to live under surveillance . Genesis discovered the abandoned caverns by chance and made his secret headquarters there , which Zack Fair will discover years later and read Genesis ' s childhood diary . After the Banora Village is destroyed by Shinra to cover up the latest incidences there , the underground caverns can be reached from above easily . Genesis uses the secret lair as his base of operations as he conducts his war against the Shinra Company . When Zack descends into the caves , Genesis uses the Goddess Materia to transform into Genesis Avatar . When Zack defeats him Genesis returns to human form , now cured of his degradation . Genesis again challenges Zack , but is defeated again . Layout . Depths of Judgement . The first area in Banora Underground .
