Ithym, a powerful guardian created by Crehare, was assigned to rule over darkness. Initially tasked with protecting mortals, Ithym grew resentful of their ingratitude. This resentment, coupled with feeling like a pawn of Crehare, led her to rebel and devise a plan to eliminate the other guardians, forcing Crehare to directly protect humanity. The shadows have overtaken the northern region of Hyacinth, prompting an investigation by the player and Hysode into Ithym's sanctuary.
