Carnos was once a simple matoran of carbon, like everyone else in his village. They had all been enslaved long ago by dark hunters and have since lived their lives mining. One day the village was approached by three strange beings. The dark hunters let them into the village.
The three turned out to be traveling salesmen, though how they came across their goods was questionable. They showed off their goods to the amazed villagers. One item caughted Carnos' attention. He asked one of the three about it and he replied that it was a Kohlii stick. It was then that the Dark Hunters leapt out of hiding, slaughtering the salesmen and taking their goods. Carnos grabbed the stick and hid it, where it remained for many years.
Eventually the village was freed by toa heroes and Carnos was free. The only thing that he owned was that Kohlii stick he'd taken. He practiced with it every day, and soon became very skilled. He was then scouted by an Onu-matoran team, where he plays to this day.
Just the Kolhii stick.
You'd better like the lower arm design. It kept falling apart. It uses one of those pieces that are on Carnos' shoulders, stretched out over the bone piece. I think this guy turned out pretty good. :D
Hope you liked the MOC and enjoyed the story, I came up with it on the spot. :P
