I wouldn't. Honestly, I don't think we need any sort of narrator. Have we even discussed a ride system? Trackless would help for mobility, and immersion, which I think would make a narrator unnecessary. Really, this ride should be about immersing guests in the worlds of these books; not informing them and outright telling them what everything is. What I would picture for flow is that mythology would be single file, opening up into proper trackless in Fantasy; almost like a building anticipating until the world opens up into the more realized worlds of modern literature. It could also allow us to have different vignettes for different cars.
