Shadow Palace

The Shadow Palace (影の王宮) is the magical space between the realm of the living and the realm of the dead.

Description
The Shadow Palace is a large black structure shaped like a castle. This magical space serves as a gateway from the realm of the living to the realm of the dead. It exists within Clover Castle, the capital of Clover Kingdom.

The ancient elves allowed humans to safeguard the magical space, but only the ten Apostles of Sephirah can open it.
