The Palgaea Shrine is a underground lair that deifies the god of evil Palgaea. Located at the foot of a volcano, its grand hall is always filled with fiery lava. There is a triangular-shaped altar at the center of the shrine, where the grand priest Kunpaetku presides over various ceremonies. This is also the place where Astaroth uttered his birth cry.

The materials used to construct this shrine are not known, however, the various surroundings statues as well as the face of the serpent spewing lava suggest that they are extremely heat resistant. No one knows whether these materials are man-made or born of evil magic.
