Is Mayor-Magistrate Asanda Home?

We moved into the building. We found an old woman sitting in a chair. Laraena spoke with her, asking after the Mayor. She said he could not be disturbed & we should leave. We said we needed to speak with him about some missing Dwarven workers. During this conversation several party members became aware of some hidden creatures on the other side of the room. Imryll cast a Faerie Fire spell on the area he heard them in, revealing 2 invisible creatures. They immediately attacked, including the old woman, who revealed herself as another snake person! We quickly finished off the group of them.
Moving further in, we found the area submerged in about 2 feet of water. Here we fought 2 large Snakes. They were quite a pain, but Argent managed to hold them off the rest of the group pulled together to heal her & finish them off. As we turned to rest we heard a larger creature coming from a nearby room. It turned out to be a huge Crocodile. It immediately attacked Argent, but then turned it’s attentions to Gazzean, swallowing him whole. We finished it off and cut him out. We then retreated to the entrance to rest & heal. Afterward, we moved in again, choosing to ignore several side rooms. As we pushed our way into a room that rose above the level of the water we met a human man with a pet panther. He introduced himself as a Mayor-Magistrate, but not the one we were looking for. He also told us that Asanda was not available. He then dropped the disguise on him and his cat, turning to attack. We made very quick work of him. We found the double doors straight ahead to be barred, so we turned to one side, heading through a smaller door. We found a hallway that led around to seemingly the same room we had just found barred. Inside we found a group of people seemingly having a party. In one corner stood one of the same type of Lizardfolk we had seen (and dispatched) out front. We questioned them and quickly became aware that most of the humans here were illusions. One of them however turned out to be real & said he was Mayor-Magistrate Asanda! There was definitely something off with him though. He seemed almost to have 2 personalities. We chose to take him alive, not worrying so much about the Lizardfolk guard. As the fight was joined, Asanda called out “Guards”! More Lizardfolk joined the fight! While it was a protracted fright, we managed to kill everyone, except Asanda, who it seemed was a Lizardfolk too. We still took him alive for questioning and just in case.
