As they arrived at Quindecim, two men found themselves grappling with a sudden and unexplainable loss of memory. A youthful lady greeted them and ushered them into a cozy little bar, where they met a bartender. However, their brief moment of relaxation was interrupted when they were informed that they were required to partake in a game, chosen through a roulette system, and stick around until its completion. Refusal was not an option, and it would have dire repercussions if attempted. They were reminded that their lives were on the line, and they must play with that in mind. The game they were assigned was billiards, but it was nothing like the typical leisurely sport they had played before. As they were soon to find out, the stakes were much higher than they had anticipated. Their very existence was in jeopardy.
