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, The body of Sir Kerrion Stonefell slumps to the ground. The rest of Vox Machina stares at Percy, who now appears to be a humanoid entity made of swirling black smoke, with the pointed tip of his mask poking through.
DM: With that, the little bit of wreathed magical energy you can barely make out an expression of horror on the face before the resounding blast sound rocks the room. The actual bullet itself a trail of black smoke behind it as it impacts the front of Sir Kerrion's face. The entirety of his head caving inward as the back splatters across the scarred wooden wall behind him. The body slumps to the ground immediately. You guys all glance over at Percy. You don't even see Percy, you just see a humanoid entity made of black swirling smoke energy with the peaked beak of his mask poking through.
Player: Not 100% sure what's going on. Can I take my Faerie Fire concentration that I still have up and move it over top of the black smoke figure?
DM: Can you move a Faerie Fire?
Player: I don't know; can I move a Faerie Fire?
DM: I think when you use it, it just stays where it was. Could be wrong, but I'm pretty sure that's how it works.
Player: 20 feet; is he in it, perchance?
DM: From there, it's 20 foot, no. Not from where you placed it right on him, unfortunately. That's okay. Yeah, no, it just happens once.
Player: Never mind.
DM: With that, you recoil from it and the voice echoes in the back of your head, going "Yes."
