These dragons branched off from multiwings very long ago and aren't advanced at all they don't even use tools

They have a great ability to dig and have a wide assortment of weaponry such as claws spines and teeth, they don't have a form of communication and see things by touch

Multiwings are the guardians of them, because they watched their species develop, each multiwing is assigned to a specific primalwing

There is however a slightly advanced group of them known as tunnelwings who have eyes and can communicate by rotating their teeth to make a noise they are led by (as the multiwings call her) queen terra and the multiwings are attempting to be able to communicate with them

Queen terra

Open tribe just give proper credit
