It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously,  Vox Machina are on a boat.
DM: Okay. Keeping an eye out, and as you move, you catch a little more of the shape in the distance. It looks a little small to be a landmass. If it is landmass, it's a very small one.
Player: Oh.
DM: But it's stationary.
Player: Oh, it could be another ship, possibly.
DM: It could be a ship, it could be anything that would be stationary. Literally, it's only because of your keen vantage point, and your honed eyesight, that you're able to even make that slight, little bump in the horizon from here.
Player: All right. Captain?
DM: As you fly down, you see her, she's at the front of the ship. She has her one hand currently on the wheel, and she's looking out, chatting to the side with one of her crewmates, and turns around as you fly down next to her. She's surprised at your immediate appearance and she's like, "Oh, (gasps) sorry, I--"
Player: You'll get used to that someday.
DM: One of these days, I'm sure. "What can I do for you?"
Player: I see something on the horizon; do you know of any masses in the area? Maybe a ship, or island, or--
DM: "Take the helm." She hands off the wheel to one of her compatriots, and she rummages over in one of the small chests to the side, and pulls out a large scroll and slams it onto a table she keeps maybe ten feet off to the right of her. And she goes through and pulls out a few instruments. Marks the sun and takes a good five minutes or so getting a really strong idea of where the positioning is. She looks down. "No, not much in the way of landmasses out here, my dear."
Player: Do you have a telescope?
DM: She goes and pulls out her particular eye glass. It's small, but functional. Glances over, and you look over in the direction and point it out. There's nothing on the horizon.
Player: May I take that and fly up? I swear I'll give it back.
DM: There's a long pause--
