@AdamKoebel If you continue with the checklist for the progression of the arc (i.e. the Goal-check-mark-thing-document from the GM prep for the live show), then there will eventually be a way to battle the Farang directly, no? When this "cure/weapon/weakness" is discovered, will you present the party with another opportunity to convince the Immortals and The Tower to combine forces and drive out the Farang directly? In the episode, it was said by Hasan that heaven had no way to destroy this things; however, we know that the Immortals are trying to find way through the Sahir. We don't know if the Tower is attempting to find this "weakness", but I would assume not because they already believe they have found a solution to the problem (burning the city). What I'm saying is if the story maintains its natural progression and the Immortals and the Ahari'sa do find a weakness, and the party is notified of this, will you present them with another opportunity of creating a 2 sided war rather than a 3 sided?
God I hope so. I really want the party to pursue this alliance/true enemy path of the arc. I think it's the most entertaining out of all of them. And MAYBE. JUST MAYBE. The Mara, Heaven, and Earth could combine forces and drive out these Farang, once and for all? Just a thought
Edit: Also I wonder if the way to stop the Farang was held in Utrix's domain? How else would he have contained such a powerful entity in a prison so simple?
