The term 'GLADIATOR's setting' is referring to an ARENA, which is a large, usually oval or circular area used for public events such as sports, concerts, and theatrical performances. In ancient Rome, arenas were used for gladiatorial combat, where two combatants would fight each other in front of a large audience. The ARENA was typically surrounded by seating for spectators, and the floor of the ARENA was often covered in sand to absorb the blood of the combatants.
