It's a fantasy role-playing game.

DM: You are Taryon Darrington, a human artificer . You are the member of the famous group of adventurers. Previously, Percy admits to Vex that he may have panicked and hinted that they had eloped together. As Scanlan realizes that they are not just betrothed but, in fact, married, Percy casts a Cone of Silence to prevent him from shouting this to everyone else.
DM: The Ioun stone actually is giving a faint glow similar to the glow that you see emanating from Sprigg's torso.
Player: Is it glowing any more than--
DM: Make a perception check.
Player: Oh, okay. That's an eight. Maybe 11, I don't know. Do I add Jack of All Trades?
DM: You do, yeah. If you're not--
Player: I really want to know. I will inspire myself, and I'll add a d12. That makes it 16.
DM: Okay. You start getting the sense, the further you walk, both your stone and Sprigg are beginning to emanate a slightly stronger glow, and so you guys begin to realize that this could be used as a path to something. You're not quite sure.
Player: Let's keep going.
DM: Okay. So everyone's going behind.
