"Ancient Celestial Beasts were beings that stood alongside the gods." Mrs. Santiago and her husband Martin Huppe were gods born and raised in the Heavenly Realm, and also in the Divine Lord Realm. Not only have they both stolen many Magic Treasures and rare curiosities, but they've also stolen some ancient texts that have never been made public.
Therefore, the two of them have a very good understanding of the Ancient Celestial Beasts.
