Lorien

Toa Lorien is a Toa of Light who was drafted by the Order Of Mata Nui during the Destiny War and founded a dangerous cult known as the Circle Of Light that took over the Order Of Mata Nui, allowing Lorien to institute a totalitarian government.

Biography
Lorien was an Av-Matoran who was relocated to Metru Nui by the Order Of Mata Nui to Metru Nui and was disguised as a Fe-Matoran. Lorien worked as a botanist, unaware of his past.

Invasion Of Metru Nui
When the Shadowed One, leader of the Dark Hunters, sent his forces to invade the island, Lorien was compelled to join the Matoran guard along with many of his closest friends. Lorien and his fellow guardsmen won and lost many brutal battles against the Dark Hunters before the unexpected intervention of the Brotherhood Of Makuta. The massive surprise attack by the Brotherhood's forces caught the defenders of Metru Nui off guard, and many of Loriens comrades were killed or had their light drained during the attack. Lorien was deeply traumatized by the incident, and became obsessed with avenging his fallen comrades. However, even his fanatical dedication to defeat the Brotherhood wasn't enough to save Metru Nui.

Recruitment by the OOMN
During the fall of Metru Nui Lorien and a dozen other known Av-Matoran were secretly extracted from the island by a deep cover OOMN agent and transported to Daxia, where Helryx personally briefed them on their true pasts, further damaging Lorien's already fragile mental state. However Lorien remained dedicated to destroying the Brotherhood, and personally requested to be deployed to the front lines after his transformation. Lorien soon became known for his courage and valor on the battlefield, and the Order chose to make him their posterchild despite his equally ruthless brutality on the battlefield. His charismatic personality attracted the attention of many, and Lorien was eventually given command over a battalion of Toa Of Light who became extremely loyal to Lorien.
