Nod Pyramid

History
Nod Pyramids were used at least twice, and were believed to be made out of steel or concrete. The first time was during the Nod civil war between Hassan and Slavik. In that conflict, Hassan used a pyramid for his command center, but was forced to flee when the Brotherhood advanced on the command center.

At the very end of the Second Tiberium War, Kane was located at a new Nod pyramid, a significantly larger one. GDI forces, including commander McNeil himself were able to defeat Nod and enter the facility, which resulted in Kane's death. The pyramid itself was capable of firing powerful missiles, such as the Tiberium Missile.

Usage
Nod commanders used the pyramid as a command center, but exactly what facilities were present inside the pyramid is unknown. Kane's pyramid is known to have contained a large missile silo where he planned to unleash the Tiberium Missile, as well as a room with a pedestal for mounting an object Kane referred to as The Tiberium Sun (possibly the Tacitus), but all other information about the pyramid is currently unavailable.
