The Hero party is getting ready to exit the dungeon at The Fool's Rapids. The OL had played the plot card "The Harbinger Approaches" at the beginning of the week. The Avatar is the Spider Queen whose Keep is at the Whispering Forest, two weeks travel from the Hero party. So, because of the play of the plot card "The Harbinger Approaches" the Hero party can travel to the Whispering Forest to initate the "Final Battle".
The rules provide a process for initiating the "Final Battle" after the combined conquest total passes 600. Is that process for initiating the "Final Battle" changed in any way because of the play of the plot card "The Harbinger Approaches"?
