I have a question about your world. You mentioned that the main gods can be depicted in different forms. Is there some common theme or symbol that will allow people to tell who they are? I'm thinking about something like how depictions of Catholic Saints can be quite different from each other, but they'll be holding an item, or something of that nature, which makes their identity clear.

That fits very well with the Scarcity of Understanding, as an overall theme of people setting off dangerous events out of ignorance and lack of desire to reconsider their beliefs.
You could also have the spirits be protective of certain creatures or plants. Maybe the party is in an area where only those sorts of things are. They have to decide between eating and annoying the spirits, or hoping they can hold out long enough to get to some other supply of food. You could also go the Greek tragedy route and have spirit number one trick the party into harming something special to spirit number two.
