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, If that fails, once their main force is on the bridge, Grog will cut the rope holding the bridge. you casts her spell.
DM: And you can actually see that the bridge looks attached to it, it's a very, very convincing illusion. And you kind of have to remind yourself that it's an illusion, just so you don't fall for it either!
Player: Yes, be careful guys, please be careful!
DM: All right. So you're kind of chilling in the middle of the bridge?
Player: Mm-hm.
DM: All right. The rest of you are--
Player: All right, I'm on the outside of the bridge.
DM: -- on the other side-- outside of the bridge.
Player: I'm out with them.
DM: Okay. So you're off the bridge now.
Player: Gone. Yeah.
DM: All right. So now, Tiberius, Vax, you guys walk across the bridge, keeping grip both side rails, feeling it rock to and fro from the continuous warm bellowing of wind up from the cavern beneath you. Eventually you bring your way across. What looks like you should be stepping on terrain is still the bridge, and it takes you a minute to adjust to the fact that you're still going across the bridge, but it looks like rocky terrain. Eventually you make it to the other side and you grab purchase on stone. Looking ahead of you, you can see about 60 feet ahead of you the outskirts of the war camp.
