Enkanomiya is an ancient underground civilization located beneath Watatsumi Island in Inazuma. It was once home to a human society that lived isolated from the surface world. Since there was no natural sunlight, the people used the Dainichi Mikoshi, an artificial sun, and lived under a controlled cycle of Evernight and Whitenight. Over time, the civilization was abandoned and sealed away beneath the sea. Now, Enkanomiya is filled with ruins, Vishap creatures, and lost records of ancient knowledge, making it one of the most mysterious forgotten regions in Teyvat.
Enkanomiya’s environment is a vast underground sea of ruins hidden beneath Watatsumi Island. Instead of natural sunlight, it is illuminated by an artificial system tied to the Dainichi Mikoshi, creating shifting states of light and darkness known as Evernight and Whitenight. The landscape is filled with floating islands, broken stone structures, deep water channels, and ancient architecture eroded by time. The atmosphere feels silent and isolated, with an almost dreamlike emptiness.
Enkanomiya is significant because it preserves knowledge of an ancient civilization that existed before Inazuma’s current history. It holds records and truths that were lost or hidden from the surface world, making it a key source of forbidden and forgotten knowledge in Teyvat. It is also important because it shows how humans adapted without the gods, using artificial systems like the Dainichi Mikoshi to survive in complete isolation. This makes it a major example of humanity existing outside Celestia’s direct influence.
