The lair of the Demons for the first half of the game. Zeikfried and Alhazad brought Mother's coccoon here. Presumably what the Demons arrived to Filgaia in, as it has flight capabilities. The Photosphere has a shielding device known as the "Soldelita" (which gives Photosphere its name) which blocks any access from intruders, and vaporising them in the process. Asgard the Earth Golem destroys the Soldelita with the help of the Rune Drives. The Tear Drop powers the place on first entry, until Zeikfried (disguised) allows the trio to reclaim it. This lowers the surveillance and weakens Mother's powers. Following Mother's defeat, the Photosphere sinks into the ocean and decays. Zeikfried is sent back to the underwater helm of Mother's throne room following the Gate Generator incident, and Mother's remains consume him.
