It's a fantasy role-playing game.

DM: You are  Kashaw Vesh, a human cleric . 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: "So please, if you would not mind making sure that they see their contract to fruition, taking them on this as you will, showing them the ropes of the guild, and try not get them killed."
Player: And for me?
DM: "Well, you will be rewarded as per the contract. You will have done the guild a great favor, which you know favors can go a very long way in the guild."
Player: I certainly do. You don't have to tell me about repaying favors.
DM: "Fair enough. Well, perhaps now would be a good time for this jovial lot of adventurers to know what it is they are to hunt down."
Player: Is it an actual group?
DM: "Well, we'll see how well you can make it into one. Perhaps this is a test for you as well, fair dwarf."
