"In Time, the two arrived at an ancient and secret palace at the bottom of the sea."
The Undersea Palace is an ancient place deep in the Moonshine Sea. Its home to the God Of The Sea himself and his mermaid citizens. Its also the location of Trident's sushi stand.
The undersea place is a Japanese style castle, built from red and white coral. A large purple crescent moon lies at the back of the Undersea Palace. The palace is decorated with mermaid statues.
- It is likely this palace is suppose to be or is direct reference to Ryūgū-jō or the undersea palace of Ryūjin, from Japanese folklore due to its many similarities in appearance and style, as well as being home to a god of the sea.
