Analect XI: Hypothesis of the Hunt

We've long held the goal of the fal'Cie's endless excavations to be the expansion of the world's inhabitable space-the creation of new lands with which to honor the gods. But I contend this to be false. Their methods lack the order one would expect if that were their purpose, and what's more, the gods they would honor have long since departed this world.

I propose a different explanation: the fal'Cie are hunting. Whether they seek a way to recall the gods or to journey to their side I cannot say, but I do believe the fal'Cie seek their lost deities. They search the earth, the skies, the waters, and even the deep places, seeking a gateway to the Divine.
