Apprentice Mage Calen shocked everyone when he disappeared--apparently willingly--with Krelig, the incredibly powerful and evil mage intent on forcing the world to submit to his rule. Krelig believes Calen will be the key to his victory and is training him to unlock his untapped magical power. Calen is desperate to escape but knows he must first learn as much as he can if there is to be any hope of defeating Krelig. In Trelian the war is going badly. As the mages prepare for their own deadly battle, Calen must find a way back to Trelian to stop Krelig before it's too late--if those he left behind will forgive and trust him enough to let him come home at all.
