I've written 2,350 words and three scenes for my Bride of Perseus story as of now. Before I begin to describe my problem, I need to summarize each scene:
Scene One: Adhiambo, an African princess who is the story's heroine, is about to be sacrificed to the sea god Poseidon's pet monster Cetus when Perseus, the Greek demigod, intervenes. Displaying supernatural strength and agility, he slays the monster and frees Adhiambo. This pisses off Poseidon, who takes away Perseus's divine abilities and reduces him to a complete mortal.
Scene Two: Adhiambo carries a weakened Perseus back to her village to nurse him back to health. While Perseus is explaining what Poseidon did to him, the hunting goddess Neith appears, gives Adhiambo a bow and quiver, and tells the two how to get to the Underworld where Perseus's divinity is hidden. Perseus, who comes from a patriarchal Greek culture, doubts that Adhiambo can fight alongside him, and Adhiambo is determined to prove his doubts wrong.
Scene Three: The heroes tell Adhiambo's family where they are going. Adhiambo's mother is concerned for her daughter's safety but lets her go after her daughter tells her that Neith has ordained it. Poseidon finds out about this quest just before the heroes exit the village and begin their epic journey.
Now comes my problem, the problem that has always come up whenever I try to write a story about characters traveling great geographic distances...exactly how many obstacles and stops should I place in between Point A and Point B? I want to convey that they're crossing a lot of terrain fraught with danger, but if I place too many obstacles, I worry that the story will end up a repetitive and formulaic series of action scenes. How much would too much be?
