Order of Mata Nui
The Order of Mata Nui was a secret organization devoted to carrying out the will of Mata Nui.[1, 2] It was formed very early in the history of the Matoran universe. Its original members were formerly of the Hand of Artakha. It was decided at the outset that while Toa would be the public face of order and justice, the Order would remain hidden so that they could do things Toa could not. It had hundreds of agents.
The Order's primary base of operations was on Daxia. All Order of Mata Nui members had orders to fall back to Daxia in the event of a major attack. Daxia was the Order's oldest and largest base.
In the Order of Mata Nui's guidebook to the Matoran universe, the timeline of Metru Nui's history was purposely incomplete for reasons which, it claimed, should have been well known to its members. This guidebook also included information about the Order's own base, Daxia, as a contingency in case the Order come should suffer a devastating attack and surviving members should require the information to rebuild.
Members of the Order of Mata Nui were expected to have familiar knowledge of the Toa Mata and their accomplishments.
The Order of Mata Nui had a library, which included the Rahaga's Rahi Beasts.
The Great Beings realized very early on in the history of the Matoran universe that there was a need for an organization such as the Order of Mata Nui. It was expected that Toa would be the public face of Mata Nui's will, earning the Matoran workers' trust by protecting them. However, the need to maintain this image implied that there would be some tasks which the Toa could not do and some which the Toa could know nothing about. Another organization, one dedicated solely to Mata Nui with no other loyalties or allegiances to interfere, was needed. Hence, the Order of Mata Nui was founded.
In its time, the Order acted only when it needed to and when the Toa could not. Their operatives checked, in part, the plans of the Dark Hunters, the League of Six Kingdoms, and the Brotherhood of Makuta. Regrettably, some of the Order's actions resulted in the deaths of Toa or Matoran for the sake of the organization's anonymity, its greatest strength. From their point of view, even saving the lives of Toa fell short of the importance of serving the interests of Mata Nui.
At the time of the Toa Mahri's mission in the Pit, the Order of Mata Nui was hundreds of members strong, with members scattered across the Matoran universe. Although outnumbered by their foes, they compensated with sheer power. The Order believed that any one of their operatives could easily overcome the Brotherhood of Makuta's servants, although members of the Brotherhood would likely be able to stand up to an attack from the Order.
No intelligent beings other than Order members lived on Daxia. The Order had no workers, servants, or slaves but instead saw to its own needs, considering it better and safer for all concerned. The Order's members came from numerous species, each bringing unique talents and abilities. All members had a passionate commitment to the Order's mission, which was essential for their work. Those who were recruited into the Order had to surrender their lives and their freedom for the sake of Mata Nui, giving up any hope of a life of leisure or the option of leaving the Order later in life. For this reason, the Order thoroughly tested potential members, in secret, before making an offer of membership. Even at the time of offering, they did not give candidates a clear picture of what they will be doing or whom they will be joining. The Order only revealed the truth when it was certain a candidate would serve with honor. Up to the current time, no one ever rejected an offer of membership. The Order also had certain other requirements when seeking recruits. They would not consider Toa, Turaga, or Matoran, since they had their own role to play in the Matoran universe. They would also not consider former Dark Hunters or servants of the Brotherhood of Makuta. The Order's recruiting methods were not infallible, as there were instances where members betrayed the Order's ideals (even before Brutaka). The Order had Botar banish such traitors to the Pit, never to return. Botar's unwavering devotion to his task and long record of success instilled some fear even in loyal Order members. Merely mentioning his name was enough to dissuade potential traitors.
The Order of Mata Nui considered the Makuta to be brutal, ruthless traitors and regretted their inability to protect the Matoran universe from them.
The Order placed agents in places of importance to monitor events. Throughout history it thwarted plans of the Dark Hunters, the Brotherhood of Makuta, and the League of Six Kingdoms, all without exposing their own existence.
During the Toa Mahri's mission in the Pit, the only outsiders who knew of the Order's existence were the Toa Mahri, the Toa Nuva, and the members of the Matoran Resistance.
The Order of Mata Nui gave members like Brutaka mental training in order to resist attempts by others to probe their minds, so that the secrets of the Order of Mata Nui would not be exposed.
Order members like Brutaka were willing to kill in order to keep the identity of the Order a secret.
The Order most likely acted on behalf of Mata Nui without being given overt direction from him. They have had access to some insider information, but they never showed any sign that they were aware that Mata Nui was a giant robot or understood the fundamental nature of things.
