Equestria, the land of Magic and friendship. While other lands have to make do with one dungeon core, while also delving into their depths to prevent an outbreak, Equestria hosts hundreds, who work for the benefit of the land, creating gems in the ground to mine, shaping the land as they wish, and making it easier for the ponies to manipulate their surroundings...
However, nobody, except perhaps the princesses, understands exactly what dungeon cores are. Nobody except one desperate researcher, the griffin Xaviar. Inside a gorge in which he had discovered the remains of an inactive core, this adventure was his last... Until he came back as the core. With no guidance except his own knowledge and his proto-magic rich environment, Xaviar will have to resist all the forces that wish to make him theirs.
