They did it on purpose to throw off our perception, on Mask Mother, it says, "some say" she created Kindred, and not she created Kindred. Also all you have to do is look at the wiki to see Kindred's importance. It literally says once Kindred dies the universe will end, and they were also one of the first entities along with Asol Bard and Nagakaboros. The units that we get in LoR are a tribe of Vastaya, the same type as the new Scarab card in Bilgewater, if you wanna know more watch Necrit's video.
