Mithra Sealed Castle

Overview
Located on the west side of Ilias Continent just south of the Nameless Slums. It is created to contain 20 unique weapons that were unintentionally created in the immemorial age, through the mixture of darkness and light that the two Goddesses manifested through their hostility against each other's existences.

This castle was created from both Ilias and Alice I to secure and contain these special weapons, but during the Great Monster Wars, when the two forces unleashed everything they had against each other, these 20 weapons were unsealed and are being used by both the two Goddesses' factions. Currently, all of them have been lost, and the castle that didn't have a purpose anymore has been banished in the void of spacetime.

However, for an unknown reason, it returned to the world and stood at the southern side of the Nameless Slums.

Trivia

 * Mithra castle is most likely named after yazata (archangel) Mithra from Zoroastranism. Mithra in Zoroastrianism is considered the most powerful archangel and the judge of human souls in afterlife.
 * The concept of a sealed castle containing legendary sealed weapons may be based on the Sealed Castle Kuza in Final Fantasy V, the resting place of the Twelve Legendary Weapons.
