Cuvitidala

Cuvitidala (カルビティダラ), or just simply called D528-143, is a location in the Demon World. The ancient ruins of Cuvitidala are the central focus and namesake of the Cuvitidala Arc. It is implied that the place was once a sacred shrine, but its use has been long since discontinued. As it has been closed down, only Emma, having the eye amulet, can use the shrine's clairvoyant abilities.

Appearance
Cuvitidala is a Stonehenge-esque structure made of crumbling rock pillars. These pillars have many symbols carved into them and are arranged in the shape of a large eye similar to the shape of Emma's amulet, which seems to be connected to the structure.

Use
Cuvitidala is one of two ways to find the Demon King. However, the Cuvitidala is limited to non-interactive visions of the past and astral projections of in the Day and Night; any true interaction with the demon king can only be made at the "Entrance" at the Seven Walls.

History
The ruins were built by ancient demons in the shape of the dragon's eye because it was believed that the dragon's eye saw everything. Cuvitidala was a special place where demons would come to worship Him. They would make shrines and leave offerings and in return, He would give them a vision of anything they wanted to see. However, at some point Cuvitidala was abandoned and fell into ruins. It is unknown exactly why it was abandoned.

Mujika
Though Mujika is never featured going to Cuvitidala, it is implied she has a notable connection with the place, as the only known key to Cuvitidala is the amulet given to Emma by her. After realizing this, Emma begins to question the nature of Mujika.

Emma
After much research in Shelter B06-32, Emma embarked to Cuvitidala and found it successfully. Accompanied by Ray, Don, Gilda, Violet, and Zack, Emma met the Demon King for the first time at this shrine.
