Cabbage: What? No! What? That's IMPOSSIBLE!
Cucumber: ...But they're right here.
Cabbage: It's boring, then! You don't want to go down as the most boring legendary hero in history, do you?
Elan: I dunno... dozens, I guess.
Tarquin: What is the one thing they all have in common? The one fact that they all share?
Elan: The hero always wins!
Tarquin: Arguable. No, the one thing they all have in common is this : The wicked empire exists. It has existed for some time, and it will continue to exist if no hero intervenes.
Tarquin: Don't you see Elan? The rules of drama to which you subscribe as a bard tell us that such tyrannies can exist — indeed, MUST exist — and persist long enough that no one realistically thinks that they can be defeated. Else, where is the drama in a hero opposing them?
