See this is where there’s a contradiction between the books and the animations. Ekimu and Makuta would have no reason to make different looking masks, because before the Great Cataclysm, all villagers looked the same, because everything was jungle. There would be no reason for them to wear separate armor, seeing as they’d all be in the same environment.
(Unless we’re considering the different colors of villager different races. That would make some sense)
####However! We do have the graphic novel coming out soon, which promises to be a prequel of sorts! Maybe we’ll learn more from that?
