Well, true, but in Hell Kingdom there were story setups to move to another route. What should happen in Timfalme route for it to change? Orphelith saying something like: "I'm tired of you, go talk with Geminigems or something just leave me alone"?
The only theoretical setup I see is the first scene with Orphelith and Cygnia in the throne room, where the Queen could assign the mission to Cygnia, thus transfering us to her route.
I wonder what kind of route would it be with that eternity old zesty mage by the way. Trolling Croixelle maybe?
