O-de Gelsiya is reality beyond an invisible line. Here magic is inseparable from life itself: it is the breath of nature, its primordial power. Magi catch its whisper, sense the call of the source, channel its energy through themselves, and weave spells from it.
At the dawn of time, the Dark Patrons learn a prophecy: a foreigner will come into their world—someone destined to strip the Dark Magicians of immortality and erase them from the face of the earth. The Lord of Death orders the Lord of Shadows to find the uninvited guest and kill them before they can raise a hand against the great ones. But the Dark Magicians can’t imagine that their doom will be an ordinary girl accidentally transported to O-de Gelsiya from a world where magic does not exist.
