I just - I don't know. That's the question I've been trying to answer.
I feel like if it were a lone warrior they'd make more fuss. We'd have seen them. But if it's not a warrior class then not necessarily. They sent Yuuzhan Vong into our galaxy decades before they invaded and those were in masquers - they looked human, or whatever species they went in as. Nom Anor was like that.
He might destroy when he could, but try to keep undercover otherwise? But if there is one, or more, even if its a handful - I feel like it's a ticking clock before its not just technology.
Are there any missing persons reports for that area? Or unusual violence?
