What to do in the Forbidden City

We have 3 options in this city of Yuan Ti 1 Try to kill the most powerful ones so they cant summon this Dark God of theirs, most risky of the options 2  Go to the King of Thyatis who is indirectly paying for this journey of ours, try to get an army come back take on the city, hopefully win the fight, rob the city leave it in ruins 3 FOrget the city and them trying to summon their god and go into N8 I believe (Another Module) and see what happens Dont really want to leave them to summon the Demon God, but, we dont really have the power to stop them at this point without fighting a bunch of yuan ti and hoping that we can get away with it

Option 1 has my vote

As I don't have N8 which I think is the hidden shrine of Tomoachan (The one with the Wyvern nest on top of it), even started with prep yet the other options are best. As to summoning an army, you have potential allies in the Grippli, (kicked out of city) and Mongrelman (kicked around by the Yuan-Ti), so far so you may not need to go back to Thyatis. I was doing prep for the RL2: Charnel Pits of Reynaldo Lazendry, which is almost done.  I wanted to redo the first module to today's standards so to speak, (Craft Dungeon of R.L.) then went and did RL2, while I then await the 3rd and possible 4th level to be released by Jeremy Reaban.  After that I can start on Tomoachan. I will just get the Yawning Portal module on Roll20 and Enhance it to AD&D.
