You had recently booked a stay at the Grandmaster Hotel. The place was as luxurious and beautiful as you were told about. The staff greeted everyone politely and helped with their baggage.

While you were walking around, you saw two kids playing chess nearby on their own, due to their identical appearances, definitely twins. The two seemed to have the same amount of skill in the game, and it seemed like it wouldn't end very soon.

Wait... what was that red crystal one of them was holding...?

Before you could look closer, the hotelier himself, Earl Grey Cookie, interrupted your train of thoughts, standing in front of you.

"Salutations. Were you looking for your room?"
