The coordination of a planetary response to the SkrallSkrallA black-armored warrior species from Spherus Magna that dominated northern Bara Magna under Tuma's rule. began the following morning. Most of the subsequent campaign against TumaTumaTuma rose from the survivors of the Baterra massacre to rule the Skrall Empire from Roxtus until Mata Nui defeated him in single combat. traced back to those caves.
The geography around Atero was already harsh, and the destruction made resettlement impractical. The river fed by water from the Black Spike MountainsBlack Spike MountainsThe mountain range north of the Bara Magna desert that served as the Skrall homeland after the Shattering, became Baterra hunting ground, and was destroyed when the Mata Nui robot fell upon it. ran south but evaporated before reaching the region of Atero. The free city had relied on stored water and trade, not a local source. Once the SkrallSkrallA black-armored warrior species from Spherus Magna that dominated northern Bara Magna under Tuma's rule. held it, there was no nearby water worth fighting to retake.

New Atero#
The original site was never rebuilt.

Their initial search failed; no site they examined seemed suitable. TahuTahu (2001)Tahu was the Toa Mata of Fire and leader of the team, from his first landing on Ta-Wahi Beach to the destruction of Teridax's Rahkshi army on Bara Magna with the Golden Armor. told his companions that earning the trust of the AgoriAgoriThe villager species of Bara Magna, organised by tribe and settlement, who governed their villages and arranged the Glatorian arena system. and GlatorianGlatorianTribal warriors of Spherus Magna who settled disputes through arena combat, until the Skrall conquest enslaved most of them. was a prerequisite to building a peaceful society, and that finding the right ground would take time.
The eventual New Atero was founded much further afield, on Bota MagnaBota MagnaA verdant jungle moon separated from Spherus Magna for 100,000 years, then restored by Mata Nui himself at the climax of the Core War.. The original Atero's desert ground was too dry, too contested, and too distant from the surviving population centers to rebuild upon. The name carried over, but the geography did not.

Frequently asked questions
- What was Atero?
- Atero was the free city at the center of Bara Magna, the only major settlement on the planet not tied to a single tribe. Built around the Arena Magna, it was neutral ground where members of every tribe could gather without provocation.
- What was the Great Tournament held at Atero?
- The Great Tournament was the annual event hosted at Atero in which the prime Glatorian of every village fought for resources and honor. It was the recognized means of settling intertribal disputes peacefully, with results binding on the tribes.
- How was Atero destroyed?
- Tuma led a Skrall army against Atero on the morning of the Great Tournament, striking during the opening match between Tarix and Strakk. The Skrall took the Arena Magna by force, killed many Glatorian and Agori, and the survivors fled to caves in the surrounding desert.
- Why did Tuma attack Atero earlier than planned?
- Tuma's original plan was to wait until the end of the Tournament, but the Baterra moving through the Black Spike Mountains forced him to advance the timetable. He needed unchallenged authority on Bara Magna before the Baterra reached the southern plains.
- Was Atero ever rebuilt?
- The original site was never rebuilt, as its desert ground was too dry, too contested, and too distant from surviving population centers. After the reformation of Spherus Magna, New Atero was eventually founded much further afield on Bota Magna, carrying over the name but not the geography.
