The Esper Saga
The Hellfire Sanctum
The Hellfire Sanctum, also known as The Lost Sanctum, used to be Ifrit‘s home in the distant past. It’s a vast, cavernous sanctum located near Mount Gulag. The Sanctum was abandoned in the Magi Wars after the daughter of Shiva sacrificed her life to shroud Mount Gulag in a barrier of ice-magic, which inverted the Magi Flow of the Hellfire Sanctum, turning it into an icy cavern. It was dubbed the Lost Sanctum by Ifrit, who left it to instead make his home in Pandemonium.
Recently, the Hellfire Sanctum was restored to its former glory when the half-Esper Gehenna imbued it with his own powerful fire Magi, which thawed it. While crude and unfurnished, its inherent Magi is no longer locked down by Shiva’s energies. It is again a place of intense fire and flame, much like the volcano nearby.
