Garyn identifies serpentine tracks that might have been left by a large yuan-ti. Martok, invisible and gaseous, goes outside and spots a harpy perched on a rooftop across the street.
The party heads back the way they came to interrogate their prisoners.
Elsa intimidates the yuan-ti sorcerer and it says that Liamae has been handed over to the harpies, so that they can force her to tell them the location of the other spies in Knossos.
The yuan-ti who escaped might have run to the harpies for help, but it is equally likely that he teleported to The Wreck, the pirate base 30 miles to the east.

They take her down to the dungeon to interrogate, but dare not remove her gag. Lukwind intimidates her telepathically and she confirms that Liamae is their prisoner.
They are also holding Vurch Udderwort, a rival drug dealer who was brought to them by Kedward Bone. He has been selling Green Welcome in the slums, in competition with the wizard.
Knowing that there are 9 harpies in total, only 3 of whom are currently at the Crooked Spire with Liamae and Vurch, the party decides to hunt down the remaining 5 one by one and kill them. With their ears stoppered with wax, these airborne harridans do not present much challenge.
with all of the other harpies dead, the party buffs themselves (and Tolin & Zan) to the hilt and prepares to assault the Crooked Spire. With his mindsight, Lukwind detects 4 monstrous humanoids, 1 intelligent undead and 8 humanoids. Rohit sneaks inside to scout and confirms that there are 3 harpies and 1 undead above a steel cage, 30ft high and 15ft across.
Halfway up the tower (15ft above ground, but 15ft beneath the cage) there is a room containing a prisoner (presumably Vurch). There is another humanoid, unconscious on the floor of the cage (Liamae). On the ground floor is a large yuan-ti abomination and 6 elves and humans.
Martok uses his wand of invisibility on everyone, then takes 6 rounds to turn gaseous again.
on the 7th round, Rohit charges one of the harpies while Martok and Elsa fly inside. Lukwind uses the wand of regroup to teleport Liamae out of the cage.
Rohit kills one of the harpies with a bounding assault.
