Sword of Akasha

The Sword of Akasha is a large and mysterious hovering temple-like structure built by the Holy Empire of Britannia and used almost exclusively by the Emperor himself. It has been said that its purpose is to "kill the gods" as per the Emperor's Geass contract with V.V., though how it will do that, or even the exact nature of the target gods, is left ambiguous. Its architecture resembles both that of Ancient Rome and Stonehenge.

The exact location of the Temple is also unknown, in all depictions it is shown flouting in billowing clouds with no land or sky in sight. It also seems unusually close to a planet, which is implied to be Jupiter. Entry to the temple seems only possible using Thought Elevators.

"Akasha" is a Sanskrit word meaning "aether", a possible reference to the element in Hindu Mythology.
