During the First Tiberium War, Nod occupied a volcanic island off the coast of the Yucatán peninsula. During the search for the missing scientists Dr. Ignatio Mobius, his daughter Sydney and Dr. Elena Petrova in the First Tiberium War, GDI attacked this base looking for intel regarding the scientists' whereabouts. The assault was led by Captain Nick Parker.
The base was built in a valley in close proximity to the volcano, which was used to provide geothermal energy for the base (and also proved to be its undoing when Sakura Obata's Comanche crashed into it). The base itself consisted of a communications center, a Tiberium refinery, a power plant, a dock and an underground storage base. It was heavily protected by island defences, including numerous SAM sites, turrets and a massive shore defence cannon.
Nod was not the island's first occupant, as ruins of a medium-sized town (or fort) are present on the island, in a small inlet. Additionally, remains of a large four-engine flying fortress (registration H-17529) could be found on the island.
