Over the comms he says "So far they seem as reasonable as you would expect, they say they just want out, which is fine by me as far as it goes. No need to escalate things just yet."
To the ghouls he says "I was serious about what I said before. We are here to help the community, and as far as I'm concerned that includes you. I'm no doctor, nor expert on your condition. I can't help the local laws, but I'm not here to enforce them or collect the bounty. I'll help you as far as I can, though obviously that does not include feeding myself or other innocents to you."
"As far as I am concerned you are free to leave peacefully, and I'll speak to my companions about it as well. One of them pointed out that the noise upstairs is likely a fire alarm set off by the elemental, so you probably don't have a lot of time unless we can get that situation under control."
"However, while you are free to leave, I hope you will let me make some calls and see if there's anything we can do to help you. If you keep just attacking random people for your food, eventually someone is going to kill you, and accidents will happen where your condition is spread to others. I can't promise anything, but I know of at least one other who seems to be getting by peacefully. I don't know how he does it, or if whatever he does will support several of you. I don't even know if he has others that depend on him already... but it can't hurt to ask."
"Now, do you know anything about what's going on upstairs? You can see into the astral plane, have you seen that webbing up there?"
