Rernahk

Rernahk is an ancient Mechanical Rahkshi of Molecular Disruption, from an alternate universe.

Early life
Rernahk was originally created in an alternate universe by a faction of unknown beings, who wished to gain control over their universe. Being an elite model, Rernahk was placed in the group's army with the sole intention of conquest. Eventually, he managed to become a figure of power within the army, and was commended numerous times for his successes on the battlefield, eventually receiving the prestigious position of senior field commander. However, the ongoing battles and conflicts fought by Rernahk took their toll on him, and he became disheartened by the destruction and death his creators wrought.

Eventually, Rernahk grew so wearisome of his life in the army, that he abandoned service to it, feeling from his creators in an effort to find peace. However, when his creators started a search for him, and eventually tracked him down. During the conflict that followed, Rernahk managed to retrieve a device from one of his enemies that could transport it's users to other universes, and in an effort to avoid recapture, used it to flee.

Matoran Universe
Rernahk then arrived in the Matoran Universe, roughly three years before the Great Cataclysm. Eventually, hebecame a bounty hunter, hiring himself out to the highest bidder in order to perform missions of theft, assassination, and infiltration. Eventually, however, his reputation was outshone by that of another bounty hunter named Skorr, and Rernahk was gradually forgotten.

Retiring from the life of a mercenary, the now elderly Rernahk retreated to a small, uninhabited island in one of the southern chains of the universe, where he remained for some time. After a time, he briefly resurfaced on the island of Versuva, investigating the past associations of the warlord who had once conquered Versuva in the distant past. Whilst his motives behind his investigation remain unknown, Rernahk succeeded in learning what he desired, and soon returned to his island, though not before taking a large group of wild Rahkshi with him.

He tamed this Rahkshi upon his return to his land, eventually becoming something of a pack leader to them. He would remain on this island for several more centuries until the war between the Order of Mata Nui and the Brotherhood of Makuta reached him. Both sides offered to form an alliance with him, though Rernahk decided to not involve himself with the war. When Makuta Teridax began his dark reign over the universe, Rernahk sent a number of his Rahkshi to infiltrate Teridax's legions as a way of keeping an eye on his activities.
