The Spectral Mask was a mysterious being with the appearance of a floating transparent Kanohi Hau that existed in the City of Silver Pocket Dimension. It existed in a dead forest near the City of Silver.
The mask was the first being Toa Takanuva encountered upon his arrival in its pocket dimension. It attempted to inform him of a village in trouble, but Takanuva cut it short and hurried off to help before the being completed its tale. Takanuva then fought off the creature there, not knowing that the city was its home.
Takanuva later returned to the mask, who informed the Toa that the beings he had "saved" were actually a species that had driven the benevolent race from their natural home. Takanuva later sought out the giant creature and made peace with it, helping it drive the invaders out of the city.
Upon returning to the mask, it congratulated Takanuva and told him of the value of not judging based on appearance. In gratitude, it opened a dimensional portal to an alternate universe.
