Running the Alexandrian Remix. My players have the Stone and two Eyes (Xan and Cas) but were almost TPK-ed as they entered Manshoon's sanctum. They managed to run out, carrying a dead PC and got her rezzed at a temple. Then they went and told Vajra everything that transpired and asked her to read their memories for proof of Manshoon's existence and location. Vajra promised to send out a call to the Order of Magists and her own Force Grey and descend upon Kolat Towers. However, I want Manshoon to have scrubbed the towers clean by the time they get there the next morning (the players only informed Vajra close to 12 hours after escaping Kolat Towers).

Using Alexandrian's notes and suggestions, the players will have to now find a new lead - Yellowspire, where they will battle some Banite priests before teleporting back to the Sanctum to retrieve the last Eye.

My conundrum is - what is the best way to have them get the Yellowspire lead?

I should mention I placed Yellowspire in Undercliff Village, since it would make sense to me Manshoon would want to keep a low profile for a bit. Also should mention, they are working with Cassalanters, Vajra and Davil Starsong and his Doom Raider Zhents as well.

My one idea is to send the summoned demon from Kolat Towers plus the three wizards to burn down Trollskull Manor, and after the PCs tracking them down or capturing them, they find out about Yellowspire?

Help me find a cool and organic way to get them the Yellowspire lead once they realize Kolat Towers was abandoned.
