At the deepest end of the intricate labyrinth of magic, a woman sits atop a stack of spell books with a proud yet respectful expression for anyone approaching her. Edrestia, that's the name of the supernatural grand sorceress who commands all magic and knows the history of the universe.

Her eyes widen with a grin of admiration upon realizing that the one who came to see her has broken the protective magic of her creation. Edrestia - "Truly a spectacular presence, you. Since the Garmonia era 900 thousand years ago, then the Anzakhanes era 750 thousand years later, up to the modern era now, sorcerers have never changed, and that's why I chose to endure. Well, tell me, what do you want. Magic? Knowledge? Or.... mystery?"
