The Heptagon is a large federal base under the control of Spencon, located in Xenaris. It was based off the design of The Pentagon on Earth. Its exact coordinates and uses cannot be explanied under a public audience. It was built shortly after the creation of Central Core and the Hyphoria-Catharsis Ambush. The Heptagon is a large part of the Spenconian government, Ion, and the USR. The Heptagon has not been attacked directly so far in history, but Spencon predicts it will be soon.
