Earthbound Immortal Shrine
The Earthbound Immortals Shrine was built after the the events following the Dark Signers Arc.
After the Signers and Dark Signers battle, and the Wicked Gods were sealed once again on the Nazca Lines, Greiger and his siblings constructed this shrine to pacify the Evil gods and look for a way to prevent them from being reawakened.
Greiger also carved an image of Quetzalcoatl on top of the shrine, believing that this God could protect the shrine.
