It's a fantasy role-playing game.

DM: You are Scanlan Shorthalt, a gnome bard . You are the member of the famous group of adventurers. Previously, When the pair reaches the outskirts of the walls, you casts Invisibility on them both. Now unable to see the eagle he's riding on, you holds her tightly around the neck.
DM: No, you don't have an immediate lead of visual recognition. In the meantime, you guys make your way. Swooping down, you can see that cluster, that murder of crows circling out. It's making a large pass over this entire valley. You take this cue as you get to within visual range of the city to cast Invisibility on both of you. Is that a 3rd-level spell?
Player: Yes.
DM: Okay. Both of you vanish from view, which is a strange feeling for you because you cannot see Keyleth, you're grasping onto something you can't see.
Player: Oh, shit.
DM: And you just look like you're gliding through the air.
Player: Can I do one of these?
DM: Yeah, you grab on very tightly.
