Located in probably the last place any person would check, the Soul Gem is locked deep within M.I.T to the point where it is even deeper within the institution than the Espada's Office. A large maze awaits those that try to seek this vault which goes deep into the ground and has passageways that go on for miles on end as they stretch out even through the desert underground. Most will find themselves lost in the many passageways that lead to no where but one with a keen eye will be able to find their way through most of the maze. The only two people who truly know the maze backwards and forwards are Senetue and Kyouga along with a select few. Though it doesn't end there as there are also traps once you make it halfway to the vault. Traps can vary from cannons that can blow people away, lasers that can slice through the flesh of those who don't pay attention and even holes that will send you back in the direction of the entrance of the maze. It will take one with a diligent mind and high dexterity to make it through this maze without knowledge of it beforehand.
