I'm afraid I'm not the most eloquent or have much time, but I will try to keep it short.

The festival we celebrate in the beginning of the fall is dedicated to food and celebration. Basically, it's a way for everyone to have fun before the weather gets cold and the rains come more frequently. It derives from a religious holiday, and...well, like I said before, I don't doubt someone from the shrine will be there to go into more detail.
