The Sanctuary

The Sanctuary was a dimension created by Ehit in order to preserve his soul.

The Sanctuary was comprised of many different realms. Each of them was unique in their appearance. Many of them housed the ruins from Torttus' ancient civilizations. There were also ruins that originated from Ehit's original world.

Ehit also collected various monsters, and gave them their own habitats to dwell in.

Although each location appeared different, they all possessed a teleportation gate in order to travel between

Ehit's lair within the Sanctuary appeared as a large white void.

History
As Ehit's physical body was about to expire, he created the Sanctuary in order to keep his spirit alive. He achieved this by wiping out all life on Tortus' western region, and using their mana to create his new home. With each era, Ehit would collect the ruins from various civilizations and preserved them in a new location.

During the age of the Liberators, Ehit rescued the Divine Beast Leviathan after it was nearly killed, and gave it its own home within the Sanctuary. Not long after, the Liberators attempted to kill Ehit by breaching into the Sanctuary using concept magic. Although they succeeded at reaching Ehit's lair, they failed in their mission due to Ehit using civilians as living shields.

Millenia later, after Ehit summoned the heroes from Earth, he decided to destroy Tortus, and use all of its mana to teleport to Earth. He transported all those from the demon race into the sanctuary, and placed them within a state of hibernation, until they could reach their destination. Furthermore, Ehit took possession of the vampire Yue in order to have a body that would enable him to move freely in the outside world. However, Ehit was killed three days later by Yue's lover Hajime Nagumo, who infiltrated the Sanctuary and managed to rescue Yue. Following Ehit's death, the Sanctuary began to break apart, due to its creation being no longer live to maintain it. Before it could be destroyed, however, Miledi Reisen sacrificed herself by using her gravity magic to cause the Sanctuary to implode itself, and prevent it from destroying Tortus otherwise.
