It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, Being the adventurers they are, they took it upon themselves to leap out into the forest of the Vesper Timberland, found and hunted down this hydra, fought it, and upon slaying it discovered that there was another group also hunting this hydra. An actually sanctioned group, and hunting this hydra is considered illegal in Vasselheim unless you had actually been contracted to do so.
DM: "As you know, my dealings with fate take a lot out of me. I'm not quite ready for another round of tellings. You see, this city, as most bits of civilization, are very eager to hear what the future has in store for them. So I'm a bit tapped out at the moment." And you can see a bit of dried blood around one of her nostrils. And if you recall last time, the process was very physically taxing on her. "Perhaps return in a week or so. And if I'm not here, I'm around."
Player: Old one, are you still willing to trade today?
DM: "Trade?"
Player: I'm wondering if you have any poisons beyond the run-of-the-mill nightshades this afternoon or morning?
DM: She stands up and reaches over, and there's a small alchemical glassware set up on the side. And you see it's cracked and old and it's been brutalized. And she pulls a very small vial of some dark, black, almost umbra-type liquid where you can't even see shine in the light. It absorbs all the light. She puts it forward. "This would be very unfortunate to find its way into the bloodstream of an enemy, yes?"
Player: What do you want for it?
DM: "A favor. Not now, but perhaps down the road."
