Mersery

Mersery is a senior member of the Order of Mata Nui.

Early Life
Mersery is a member of the Mersion species. He was orginally a scientist on his home island of Versuva. However, his home island was soon attacked and conquered by being known as The Shadow. On behalf of his people, Mersery asked the Hand of Artakha to help his people fight off The Shadow and his forces. The hand agreed, and with the help of some of Mersery's creations, managed to fend off the invaders, The Shadow however, managed to escape. Seeing that his talents could be put to better use, Mersery joined the Hand and came to know some of its members very well. Mersery served the hand for 100 years before it was disbanded and he then became a wonderer. Mersery soon returned to his homeland and continued to design several chemicals a viruses.

Order of Mata Nui
Eventually, former hand member Helryx offered Mersery a place among the Order of Mata Nui. Mersery accepted, and was recuited soemthing as a warrior-scholar, known for his abilities in both analysis and sword-fighting.

years later, Mersery helped several Order members modify Ehlek's species in case the Brotherhood of Makuta ever rebelled. The project was a failure and Mersery withdrawed from the experiment. Later, Mersery particiapted in an experiment on a Toa called Hydros. The project's goal was to create a type of Toa that could survive in a wide variety of environments so they could be better prepared to fight the Brotherhood of Makuta. The project worked but had draw-backs that caused the Order to scrap the experiment.

Later, Mersery helped the Order scatter the Av-Matoran throughout the universe during the erased six-month period known aqs the Time Slip.

Later Toa Tuyet was captured for murderuring several Matoran. During the battle which led up to her capture, the Nui Stone was destroyed and fragments of it were embeded in her armor. Whilst Lhikan and Dume debated on a suitable punishment for Tuyet, Mersery gave Botar a Kanohi Olmak and the he took Tuyet to a dimension where no Toa existed. Mersery was given the Olmak and captured a Tuyet from an alternative universe and placed her in The pit in order to decieve lower-ranking Order members. Mersery later began to interrogate her in order to learn from her its secrets to produce more Nui Stones. Mersery was soon relieved of this duty when Mersery was needed for other missions.

Mersery later observed the experiment performed on Jerbraz to give members additional powers. However, the experiment went wrong, and Jerbraz was turned invisible, along with a sword he was carrying.

Later, Mersery was on Zakaz when a dying Tahtorak revealed that the Tahtorak on Zakaz plan to wipe out the Skakdi.
