Callum won't inherit the throne of Katolis like his little brother Ezran, and he prefers drawing in his sketchbook to wielding a sword. His biggest dream, though, is learning the secrets of Xadia's primal source magic. That's where this sketchbook-turned-spellbook comes in. These pages hold Callum's notes and drawings of his friends, enemies, dragons, elves, other creatures of Xadia, and most importantly, everything he knows or seeks to know-about primal source magic. His friends Ezran, Rayla, Claudia, and Soren have added some of their own notes, too. Features original concept art not found anywhere else; a must-have for any fan of the show!
