With Paul Clericus Nemorian’s threat level established, let’s see how dangerous Diabolian has become.
Diabolian has remained a level 9.5. Unlike with many characters who have remained stagnate over the time Secrets of the Past takes place, this lack of progress isn’t a fault of his. Diabolian is literally so powerful, there isn’t much else he can do to become more so. He has maintained his rule over Ardesco, which is no small feat. He is an excellent fighter, as most Ardescans are, and his Temporan powers are among the strongest of all time. The only real threat he faces is Delitor, and Delitor can only defeat him if he joins with others, in particular Emma. While Delitor has proven he can do this, Diabolian is crafty enough that this is no guarantee of victory either. He is the most threatening Temporan during this time, and for good reason.
