Ahkmou (CDB)

Ahkmou was a treacherous Po-Matoran, and later a Toa of Shadow. He is currently within the Timeless Reaches.

Metru Nui
Ahkmou was a carver, and builder of structures. He carried disks that could undo minor mistakes during the carving process. He became one of six Matoran who knew the location of one of the six Great Kanoka Disks.

Such knowledge was kept hidden from other Matoran for quite sometime. But Ahkmou couldn't hold it in - he had to know if others knew about the other disks. So he devised a plan. He went into the middle of each Metru and carved a little picture - a Kanoka Disk with a question mark inside. He placed a carving detailing where to find a safe meeting place beneath the carving.
