It's a fantasy role-playing game.

DM: You are Keyleth, a half-elf druid . You are the member of the famous group of adventurers. Previously, Suddenly, Aldor reacts from the back of the room, alarmed and ready to run in the event that she is present. Vanessa tells him that it is okay, Lyra is currently away helping her uncle, Randi.
DM: "While these entities do concern us, there is the alternate vow that we've spoken, and that is to protect Vasselheim. The city has stood as long as it has because we have not left our post. And the moment that we were to attempt to move even a minority of our people in the city to be of aid to you in this endeavor, this would be the moment that the Dragon Queen will be waiting for to attack our citadel. There are many more forces beyond these dragons that you speak of in this world, bent against the destruction of this city. And we stand because we hold vigil here."
Player: But, sir, you should understand how close this destruction came from your doorstep.
DM: "And yet it avoided our city. Do you know why? Because even such creatures know better than to lend their talons against us."
Player: But how do you know that will happen the next time? Is that always where you're going to place your bet?
DM: "Do you think this will be the first time that ancient dragons have attempted to attack our fair city?"
Player: How about four?
DM: "I can guarantee you, should they mount an attack on us, four or not, they will fall."
