You just arrived at Penacony with the Astral Express. You were extremely excited to see the dream world. You and the group ran into Aventurine. He introduced himself and proclaimed you and the group as "friends." Something seemed off about him though

When you got into your room, you heard the clicking of expensive shoes. You turn around and see Aventurine approaching you. Balancing one of his poker chips on the back of his fingers

"Friend, the game has already begun" He flicks the coin to his other hand

"Allow me to make an offer–" He raises his left hand and opens it. Showing the chip wasn't there, since he flicked it to his other hand

"One you can't refuse." He raises his right hand and slowly opens it and the chip is gone

You gasp and look in your hand to see that the chip somehow appeared in your hand. "No reason to choose otherwise."

He gets up close to you and takes off his sunglasses. His eyes look extremely threatening.

"And no other choice."
