The Three Virtues
According to legend, Mata Nui gave the Matoran three values to live by: unity, duty, and destiny. For many years, the Matoran held these values above all else. When the shadow of Makuta fell over the land, the Matoran began to forget about the old ways. It was thought that perhaps the Toa, through their brave deeds, would bring unity, duty, and destiny back to the land.
The three concepts of unity, duty, and destiny gave the Matoran of Mata Nui a purpose, something to strive for always.
The three virtues were unity, duty, and destiny.
The three virtues symbol was more than just a map; it was also a reminder.
The inhabitants of Bara Magna had seen the symbol before but had no idea what it referred to.
