#onin

Onin was born blind and mute, therefore, the Precursors spoke to her and gave her a gift of light eco, so that she used her gift for good, and was, like Samos and Damas, a key person to guide Jak on the good path of his hero journey. Meanwhile, the voice Maia heard was not the voice of dark creatures who used to be Precursors: the Dark Makers, who tempted her and Gol to the dark side. On the one hand, this would cause the future, Jak and Daxter to have to embark on their path as heroes and become stronger, but it would also be what would trigger Jak and Daxter to find the Rift Gate and with it the metalheads could reach their world, destroy, conquer, and later the Darkmakers might also come to that world and destroy it.

However, it's true Onin came to do things that can be considered not very good, since it was she who told Erol that Jak was "special" and that is why the KG took him to prison, but we need to remember that the Precursors are gods who play with people as game board pieces, So Onin knew that Jak needed to go to prison to gain the power of the dark eco to defeat Kor, in the same way Samos also knew it was necesary Jak needed to go to the past and later go to the future.

And in certain way, Samos also is a opposite parallel to Gol, both being sages with an important role in Jak's journey. In both cases, we have a sage and a sorceress.

It was necesary that also Jak had people in both sides of that coin that helped him to become in the hero Mar. Since he achieved both eco powers: light and dark. That's whay the Symbol of Mar represents: the balance.
