“I've always known who Fy'ra Kai is. She's my sister, but she's also always been, how do you say? A bit of an asshole. But I never thought that she would, that she would want to kill me. I don't know who she is, and she has been so much a part of who I am, even when I thought she was gone.”-Fy'ra Rai
So the Dominox is D and the Aeormatons right? I don’t think “take up root” is a phrase that would be used for one creature, so it stands to reason its a colony of creatures or an organization.
