Or maybe they loved the story so much they wanted to become "one" with it More on topic, I believe the mask you all are discussing is the one made by Nuhrii in Metru Nui, the mask had a small hairline fracture in its chin. For further note, this was a powerless mask, designed for Matoran use, not going to be infused with power. I assume that a hairline fracture would make the mask unusable, whether it was just being used for breathing or for channeling power.
