Archivist
A Matoran keeper of records and relics, the Archivist held one of Metru Nui's deadliest jobs.

Archivists worked in the depths of Onu-MetruOnu-MetruThe deep archive-city that made mining and historical records preservation the beating heart of Metru Nui., tending to an enormous repository of objects and preserved RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts.. It's the kind of job that sounds important until you realize it was also one of the most lethal occupations in all of Metru NuiMetru NuiThe city beneath Mata Nui functions as the Great Spirit's brain, housing the Matoran whose labor keeps the god alive.. Many Archivists never made it back from their shifts. The Archives were a maze of tunnels and storage chambers, and what lived in those lower levels didn't distinguish between catalogued specimens and living MatoranMatoranThe most abundant species in the Matoran Universe, chosen by Mata Nui to inhabit and maintain his cosmic body..

The Archives and the Role#
An Archivist's work centered on the Onu-MetruOnu-MetruThe deep archive-city that made mining and historical records preservation the beating heart of Metru Nui. Archives, a sprawling underground complex that served as Metru NuiMetru NuiThe city beneath Mata Nui functions as the Great Spirit's brain, housing the Matoran whose labor keeps the god alive.'s repository of knowledge and living specimens. Archivists catalogued objects, maintained preserved RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts., and guarded records that couldn't be lost. The work demanded precision, attention to detail, and knowledge of a facility that was genuinely massive in scope. But the Archives weren't built for comfort or efficiency. They were built from interlocking tunnels and levels, with storage chambers stacked beneath storage chambers. New Archivists had to learn the layout while contending with the RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts. that made the lower levels their home. Some areas went so deep and stayed so remote that few ever ventured there and returned unchanged.
Why Archivists Vanished#
The Archives weren't just complicated. They were deadly. RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts. in the lower chambers actively hunted intruders, and Archivists conducting routine expeditions were attacked and killed without warning. Others became disoriented in the tunnel networks and were never found, lost in the darkness with no way to navigate back. Some Archivists, upon realizing they were truly lost, simply remained in the Archives for the rest of their lives. Rather than risk the dangerous climb back through hostile tunnels, they chose to spend their remaining years cataloguing and preserving in the repository they'd devoted their careers to. Death in the Archives wasn't always violent. Sometimes it was just the acceptance that the maze had won.
