The Fifth Vertex is an ancient underground shrine built to serve as the Fifth Corner of the Machine.
History[]
Early History[]
A long time ago, a race of super-ancient beings built the Fifth Vertex of the Machine beneath Diego Garcia (the exact geological status of it at the time is unclear).
During the periods that Diego Garcia was under French and British control, both nations made their own attempts to reach the bottom of the Fifth Vertex, however they would always set off the trap system protecting it.
When the U.S. Government bought the atoll from the British, they made it a naval base. The atoll's Vertex was under their control for years, during which they made several of their own attempts to reach the inverted pyramid's peak, however they fared no better than the French or British. A pair of cranes was eventually established on the rim of the ancient shrine that allowed scientists the examine the inverted pyramid closely.
During the early 21st century, the Americans' expert on the Machine, Felix Bonaventura, began examining the inverted pyramid of the vertex, and he was able to learn much regarding the other Vertices because of the symbols carved into its flanks.
The Five Greatest Warriors[]
In the interim between the laying of the Second and Third Pillars, Wolf and his CIEF forces based themselves out of Garcia's naval headquarters, further examining the Fifth Vertex and its inverted pyramid.

After the final Pillar was placed at the Sixth Vertex beneath Easter Island, the Fifth Vertex activated once again. This time, as the beam of light it emitted struck the Earth's iron core, it was accompanied by the light beam ignited from the other five Vertices, causing a series of harmonic waves that repelled the Dark Sun.
Features[]
The Realm of the Sealords[]
There is a set of paths through which the Pillar setter must have the Pillar itself to reach the bottom safely. If the master trap is set off, a wave of water enters circular shape cavern and runs around it, picking up the intruder and washing them into the abyss below the inverted pyramid.
Inverted Pyramid[]
Like every other Vertex, there is the inverted pyramid of the Machine, set above a seemingly bottomless chasm.
