Battle of Sorcerers
At some point in time, Felix Fast acquires a magical orb and a spellbook, required for his designs. Sadly for him, other sorcerers are also after the two possessions. Particularly, Rothbart's associates, Clavious and Zelda, track down Felix Faust, hoping to take advantage of the possessions for their own effort to reach Rothbart. Before his eyes, Clavious absorbs a small portion of the orb's powers to fuel his powers. However, Felix destroys the orb, before Clavious can obtain the orb's full power. Still, Clavious blasts Felix, with the little remain power he has acquired, besting him out in a battle of magic. Clavious and Zelda then take the spellbook and make their escape.
Beaten after the fight, Felix is found by Nox, a time-traveller, who seeks the sorcerer and forces him to show him an alternate way of travelling forth in time.
