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, Two shadows step into the alleyway so she quickly cancels the spell and continues walking. She hears footsteps following her.
DM: As you exit the building and turn right and into the alleyway, being careful not to be seen in your tiefling form, begin to cast the spell as you see two shadows step into the entranceway of the alleyway.
Player: Nope. I stop it.
DM: Okay. So you stop it?
Player: Yep, and I just kind of keep walking.
DM: You just keep walking? Okay. You don't even look back, you just keep walking?
Player: Yes.
DM: Okay. Keep walking, and you hear footsteps behind you.
Player: I start blocking around.
DM: Okay. As you go blocking around, the footsteps seem to be keeping pace with you. There's two sets of them.
Player: Peek over my shoulder. Do I get a glimpse on who they are?
DM: You see what appears to be a squat, kind of tan-skinned dwarf-like figure.
Player: It's the dwarf again.
DM: The features, like you expect to see a dwarf, appears to be a female dwarf of some kind, but there's some sort of physical alteration's taken place. They look like they've been either very injured and healed wrong, or some sort of corruption has taken place. But it's walking forward with this hobbling gait, and to the left you see the other entity that is just wrapped in chains, and they're about 30 feet behind you.
Player: 30 feet behind me?
DM: About 30 feet behind you, yeah.
Player: Are we alone?
DM: It's just you and the two of them right now. Just in this small alleyway off in the building that's immediately adjacent to the structure where you're staying.
Player: I'm still, I imagine, within range of the tavern?
DM: Yeah.
