Lore
The Atlantica ocean platform was known as the UAC's primary climate and environmental research station. Hundreds of scientists and engineers produced critical work there during the earliest days of the worldwide energy crisis before Argent energy was introduced.

The existence of a second facility below, cloaked in the depths of a deep trench, was kept hidden to everyone, including the workers on the facility above. The concealed lower structure houses the original body of the Seraphim, stored there after he transferred his consciousness into a cloned human body in order to move freely within the populace.
