It's a fantasy role-playing game.

DM: You are Tiberius Stormwind, a dragonborn sorcerer . You are the member of the famous group of adventurers. Previously, He, Grog, Vex, and Scanlan go through it to Kraghammer. They emerge inside the Thunderbrand estate and are met by a grumpy Lord Thunderbrand, who had stayed up all night waiting for them.
DM: "It's funny, because I already did. I gave you a permanent entry to my own household, my family's household, by offering you this sigil, that gave you entrance to the interior of our well-guarded estate. That was a trade enough. That was what we agreed upon through the mirror."
Player: That was just to get me here quicker, I thought.
DM: "So you come into my home and try to extort me?"
Player: No, not at all! Here's what happened, see. We were on an adventure-- I pull out the carpet out of my Bag of Holding. And this carpet was enchanted once with the ability to fly, and it helped us many times in many adventures. It was de-chanted, I guess, if you want to say it. And we need it re-chanted. And I thought that House Thunderbrand would be a strong enough house to have the ability to do such a thing. Maybe not as it seems. And I hand him the amulet as I'm saying this.
DM: He takes the amulet.
Player: And not as a trade, but as a favor for just the effort, or maybe because I'm not strong enough as a sorcerer myself to do it.
DM: Make a persuasion roll.
