"Perhaps that will be acceptable," the voice calls out, and then disappears. After a moment of awkward silence, you hear a door open in the entryway you first came through from the rear.
Then a figure appears through the door you entered. He is an older human. Twice your height, slender, surprisingly well trimmed beard, close cropped hair, all white. He seems at ease and calmly strolls towards you slightly, stopping within 15 ft of you.
"You'll understand if we don't trust you entirely immediately, coming here uninvited. You're alive, because no Zuffen would willing be near anyone Plovin likes, and will stop hiding eventually, when ready. Mostly it's a matter of feeling safe for them, hard in this place with the bounty on their heads.
This room has a certain feature of course. The people who built it long ago thought someone might take over the ground level, or try, so there are murder holes where you can fire down from the ceiling. That's why I'm not afraid, and why the Zuffen here should feel safe and able to tell me if this goblin can be trusted or not. He can't hurt us without being shot repeatedly himself. It's as safe as ever it can be here."
Throlu comes out calmly and states simply and easily, "He saved my life."
The old man turns to the newly revealed Throlu, "And you're sure he isn't a trap. I know he doesn't have the slave mark, so he may well not be from here, but are you sure he's not a spy or loyal to Plovin somehow?"
Throlu states, "He has no love for Plovin. I saw him kill 2 orcs and 3 slave hunters with that club. He could've easily turned me in for the bounty. He didn't."
The old human considers this for some small time before saying, "Maybe you could be our ally. If you'll work for us in helping against Plovin, then we might be able to get you to other goblins if that's what you want. You might be given rest, shelter, safety, food, yes we even have one of your termite mounds here, if you do. Take from Plovin; give to us."
He looks at you wondering what if anything your answer might be. The air is slightly heavy under his gaze.
What do you do?
