Treasures of Aht Urhgan Mission 20
Teahouse Tumult
A long cutscene with Gessho plays out in the teahouse.
Once you've gone through all of the options and the scene finally ends, head out into Wajaom Woodlands and go to area G-7. Zone into the Aydeewa Subterrane for a cutscene.
Head further in to E-9 and head down the Western slope. When you enter the next room, find a blank point just ahead to your right. Check it for another cutscene. (Watch out for tigers in here if you drop Invisible to check it.)
