RoW part 9, act 2

We are looking for one more player in our club, we play RPG's Pathfinder 1e, and some 2e.

Recap of part 9, act 1.
The party decided to go through the door in the hallway instead of investigating the sounds at the end of the hallway. Once they opened the door the stench almost made them cough, the room was like a sewer, the floor covered in putrid water. Inside the room they ran into a hostile tree creature called a Tendriculos, and a half-fiend satyr. Zaur went into attack in dino form along with Gutrender, Walker, and Ozzy’s summoned Ankylosaurus. Legifer made his way into the area, while casting bless on the party, as Arcelia shot at the enemy with her bow. The party was able to take down the two creatures and found some treasure along the way. After healing they decide to investigate the noise at the end of the corridor they passed on earlier.
They made their way into the room where they discovered 6 demon creatures called Andrazku, 2 are having a boxing/wrestling match while the others cheered them on. Walker tries some diplomacy and sets up a match between the two parties. The Andrazku go large, and the party does some buffing of their own. The demons charged but Zaur with his reach was able to hit and grapple them before they could attack. Gutrenders wolf was able to trip one, and the party attacked the grappled, and tripped demons. This went on for a few rounds, until the party finished them all off. Zaur found a trap that was on a chest in the room, but it was a poison trap and Zaur is immune, so he just smashed it open to get to the treasure. After healing, the party headed back to the sewer room and went through the other door in that room after Zaur listened and didn’t hear anything.
Zaur and Arcelia go through and find a large room with a curtain type structure sectioning off most of the room. Zaur detects magic and gets a few hits, in Dinosaur form he was able to see over the top of the curtain, and spotted what looks like three separate bedrooms, and he also sees a human female peeking through the curtain at him. Legifer tried to detect evil but did not get a reading. The creature casted fogcloud to block off the sight of Zaur. The party tried some diplomacy again, and they were able to start a parley with her. Caigreal told the party she was a prisoner but escaped and was looking for a way out. The PC’s asked if she had seen any witches, and she tells them the warden of Artrosa is a witch. Caigreal goes on to tell the party that she is evil and cruel. Then they asked her what she was doing here, and she said she sneaked in out of curiosity. Her story was falling apart when she could not give good answers as to how she got past the tree guardian, and Walkers, Zaur and Arcelia were sensing her story was untrue. Caigreal thinking the bluff was not working backed away and tried to leave casting invisibility and going out through the curtain. Arcelia was able to tag her with hunters prey making her visible to herself. Still trying to get away Caigreal moved back and forth, but Gutrender and Walker were able to keep her blocked off, as Legifer blocked one of the exits. Eventually realizing she was trapped, Caigreal started to channel negative energy, dropping her invisibility. She got off a few channels before going down, and then returned to her normal form of an Annas Hag.
