The runes are written in the Great Being language, and they tell about journeys of Artakha. The mask is a reference to well-known forms of the other ones, and I like to think, that Artakha created them according to his own, as he insipred by it.
I really like this entry. I like how the mask of creation is similar to the Hau since many believed he was Mata Nui and Mata Nui was represented by a Hau.
Maybe it’s the other way around and he keeps designing Haus to look like his mask.
And then he got to Lhikans Hau and was like “Are you sure they got the reference? Maybe I was too subtle.”
And then he made it painfully on-the-nose.
