The Arena of the Mind was a huge amphitheater located outside of the capital city of Ropagis on the continent Forethought on the planet Ropagi II. It had excellent acoustics, translation facilities and seats for around 10,000 beings. Ropagu intellectuals came here to face off against each other in philosophical debates, but guest speakers from off-world were invited as well. For the peace-minded Ropagu, the arena was a sacred site and never placed any guards there.
