Climb the tower. Get the spells. If someone wants to become a thaumaturge, master of the most powerful magics in the world, there's only one way to earn that right: do everything. Slay elemental monsters. Complete the Elemental Trials. Take on the miles-wide tower that holds up the sky itself. Lochlan Celes is determined to prove himself, and little things like no one having returned from the tower in the last century won't stop him from gaining the power to undo a terrible wrong.
