Canonically, Myron's headmaster possesses an artifact that depicts destiny. So I'm just weaving in how Myron is being sent to kill Corban because Corby [i]accidentally [/i]would have destroyed [b]the entire world[/b] otherwise. I know it's a bit much, ey! But it's the best darn reason I can think of to make a passive character of mine commit to battle.

A powerful archer and a rift rune is used in Myron's intro, but Corban won't see any more of that throughout the battle, I assure you.
