First 6 Idea!

I can’t believe anyone is talking about this. Tarin is reciting his lineage on one of their flights and he talks about his elder named Thareux WHO WAS THE FIRST BLACK DRAGON TO BOND. This means Thareux bonded with one of the first 6 and gave a signet. Thareux means EARTH in French! One of the first 6 might have been an Earth or Rock wielder!!
