It's a fantasy role-playing game.

DM: You are Caleb Widogast, a human wizard . You are the member of the famous group of adventurers. Previously, As you does this, he has to have complete concentration. As Frumpkin flies above the lake, he sees two islands within the lake.
DM: As you concentrate, the bird's-eye view of Trostenwald-- Frumpkin carries up high into the air. For the large lake that it is, you can see two smaller land masses in the center of the lake. Technically not north from where you are now, since you're back in the city, it's more of a northeastern direction. They're both relatively small, one's maybe a few hundred feet across, another one is maybe 50 feet across. It's a smaller mass. Watching as it coasts downward and does a pass over the larger one, make a perception check for Frumpkin.
Player: That is a six plus very little or nothing, so you can guesstimate.
DM: There is a faint treeline on this island. The island has a few small trees, which is mainly what you had seen during the night when you looked out over the water, Beauregard. The land mass was actually the very top of this tree line. It's a small grove that has clustered there on the center of this island. Unable to make out any other details other than the tops of these trees and there's a few spots in between where you can see overgrown grass and general ground, rock.
Player: This is the bigger one?
DM: The bigger one, yeah. Make a perception check for the smaller one.
Player: Worse. Five.
DM: The other one has maybe five or six trees on it, but most of them appear to have either died or be standing alone on this small mass. That one looks pretty barren. Even with as bad of a look as that was, it doesn't look like there's anything visible on that land mass.
Player: Does it look balder than the other?
DM: It does.
Player: Okay.
DM: The larger one has much more of a cluster, a grove.
Player: Last question, I can probably tell how far apart these two islands are, yeah?
DM: Yeah, they're roughly 600 feet apart from each other.
