Olkren is the Makuta prætor of the Northern Region of the Midwestern Islands. This region includes the Domes overseen by Boeax, Karvas, Keitos, Quozek, Sinosis, Tarel, and Zethrakk, among others.


Olkren was brought into being approximately 100,000 years B.G.C. by the Great Spirit Mata Nui, using a pool of the substance known as Antidermis located somewhere on one of the Southern Islands in the south of the Matoran Universe. As was intended, he became a member of the Brotherhood of Makuta, an organization devoted to serving the will of the Great Spirit and maintaining order. Olkren was responsible for creating several species of Rahi to populate the universe.

After the Matoran Civil War on Metru Nui, Olkren was assigned by Miserix to monitor the several domes within the Northern Region of the Midwestern Islands.

When Teridax demanded a convocation to reveal his plan, Olkren agreed to go along with the plan.

Olkren, like the other Makuta, evolved beyond the need of a physical body, turning to a simpler form of Antidermis within armor. Teridax ordered the Nynrah Ghosts to come to Destral to modify his armor to accommodate for the new virus-like form of the Antidermis.

Olkren abandoned many of his duties as a prætor and instead chose to rule over half of the Dome of Kaiva Nui alongside Karvas. The two were an inseparable duo who chaperoned the many varieties of Rahi and the numerous Matoran villages on the Isle of Kaiva Nui until suddenly, without warning, the Reikia appeared and started to drive the island's inhabitants mad. Mutated creatures and Matoran alike started to wreak havoc across the land, quickly taking over the Makuta's lairs. Transformed by the Reikia's evil power, the creatures were practically unstoppable, attacking in mass hordes at the Reikia's will. The pair of Makuta were unable to resist this force, and fled the island, marking it as a forbidden place, only to be visited at the risk of one's own life.
