The immense amphitheater known as the Arena of the Mind stood just outside the capital city of Ropagis. This arena was situated on the Forethought continent of the planet Ropagi II. Equipped with superb acoustics, translation capabilities, and seating for approximately 10,000 individuals, it served as a venue where Ropagu thinkers engaged in philosophical contests. Additionally, it hosted guest lecturers from other worlds. Esteemed by the peace-loving Ropagu, this arena held a revered status and was intentionally left unguarded.
