"Once it was the largest and oldest arena on Bara Magna. But now the Arena Magna lies in ruins, victim of a Skrall attack that shattered the thin balance of power on this desert planet.
Constructed by the Agori for sporting and civic events, this was also the only one that existed prior to the planet-wide disaster 100,000 years ago.
Arena Magna was located in the “free city” of Atero. During the chaos that preceded and followed the disaster of a thousand centuries before, Atero was declared an area off-limits to any raids or invasions. As such, it became a symbol of the peace everyone hoped for someday, but had largely given up on ever thinking would come. Although its status is largely a thing of the past – bone hunters have no hesitation to strike at or around Atero, for example – it remains an important place in the hearts of Agori.
The arena was located in eastern Bara Magna, between Vulcanus and the domain of the Skrall."
