This webtoon is a fantasy adventure set in an ancient-Egypt-based setting where people use magic crystals called "Cryst" for many aspects of daily life. Gunzin Patolk is raised in a temple being told they are the child of Anubis. The priests tell them that their affinity for Yellow Cryst means they're destined for great things, but Gunzin doesn't really know their father nor what their powers mean, and they certainly don't know what awaits for them in the dark.
