It's a fantasy role-playing game.

DM: You are Percival de Rolo, a human gunslinger . You are the member of the famous group of adventurers. Previously, As they rush to catch up, Percy trips over the uneven group and landing hard on his elbow. One of the golden-armored imps hears the sound and comes to investigate.
DM: Doesn't-- So as you guys are moving along, watching Vasa, Vasa eventually gets out of sight for a moment and you all stop and pull back. And you see a flash of light that signifies Vasa calling you forward and that it's safe. And as you all move forward, you watch as Taryon and Percival were both looking behind, keeping watch on your back, and by the time they look back you guys are already about 20 feet ahead. And as they rush forward, Percival straight up-- His foot hits the edge of where two of the iron rifts in the ground, the plating that meets up this part of the alleyway. He stumbles forward, landing hard on his elbow and giving out a (groan) of his breath. And as he does, you hear a (imp sound) and you watch as a small, impish creature in golden armor begins to crawl over the roof of the nearby building and look over the side.
Player: I turn and break away from the group and head in a slightly different direction for a moment and sit and nurse my elbow, and try and just look like I'm dealing with my medical issue and really try to look like I didn't notice the thing that's watching me now.
DM: Okay. I want you to go and make a deception check. No, you have to roll if it's intentional.
Player: Meh. Deception?
DM: Yeah.
Player: Nine.
DM: Nine? Okay. So you watch the creature (imp sounds) and slowly crawls along the top of the roof, as you go and split off from the rest of the party. You hear behind you the (imp talking) some sort of conversation, and then a second one appears. And one continues to follow you, while the other one continues to move with Taryon.
