If we kill them, then the calamity will vanish along with them!” Witches are executed one by one. But one day, as madness seizes control of the world, it is suddenly overrun by “Curses.” A country incinerated by hellfire. A kingdom consumed by crystals. An empire purged by the Tree of Life. Such are the woeful desires of those who are called “Witches of Qlipha.” Without any means to defend themselves, nation after nation falls into ruin, until finally— The fractured land is sent adrift high into the sky.
