Makuta, Toa of Shadows

As a way to redeem himself, Makuta creates a new suit to atone for his sins, now as a "toa" he will have a new duty.

When I was a child I used to think about what would be the next in the story and if Makuta could fit in, one way was to bring him in as a guardian, a protector and make him an anti-hero, with a journey not only through the new world but within himself and understand that shadows are not the same as darkness.
