Was Savage actually another child of Talzin? I always thought it was ambiguous as the Dathomiri tended to throw around familial terms (brother, sister, child, mother etc.) fairly loosely.
Feral and Savage seem to be intended to have been actual brothers: "I am your
kin". It is said of Maul that "a few still remain in his
bloodline". These things make it look like the term "brother" in this context actually connotes a biological familial relationship in a way that the use of "sister" ( as a term connoting only membership in a group calling themselves Nightsisters ) and "Mother" ( as an honorific to refer to Talzin's title as leader of the group ) do not.
Either way, he *couldn't* have had much of a midi-chlorian count as he wasn't a force user prior to his transformation.
The question is whether or not he was a Force
sensitive prior to his transformation. And I don't think we have enough evidence to say that he was not. Absence of evidence and all that...
Indeed, his last words to Maul were "I'm not like you. I never was..."
There is arguably more than one way to interpret that.
Skywalkers aside, just about ever Sith and Jedi we know of came from non-force using parents.
If that's true, when the subject of Anakin's apparent Force strength comes up in TPM, why does Qui-Gon immediately ask who his father was?
In fact, we really know very little about the parents of the vast majority of the Sith and Jedi that we know of. We assume much.
Yeah, they're a bit inconsistent on this point since I'm sure I've seem either Filoni or Hidalgo say quite the opposite.
Filoni talks out of both sides of his mouth on the issue. ( This should not surprise us too much; after all, this is the guy who claimed that Han can't understand Chewbacca. )
When asked if Orphne is a Force user, he replies "absolutely not".
But then...
"...I mean, in a different way of looking at it, Yoda would seem magical to R2 and 3PO also. Now you say, 'Aha, that's because he's a Force user'. But Orphne is not the same as Yoda.
She's probably very in touch with the Force, but she's not as like a Jedi. She's more into the, kind of from the realm of the Mother Talzin, it's the magic users,
there's ways to use the Force other than Sith and Jedi but you're not really a Force wielder, you're just really in tune with nature and things come naturally. So some of her abilities that you see, moving very quickly, that Orphne does is just based on her physicality and the type of alien she is, and the way that she can turn seemingly into little magic fairy balls - that's a little bit more of the kind of magic we see the Nightsisters using, but Orphne's more on the good side of it than the bad side of it."
^ This is basically saying the same thing I've been saying. Orphne's not using the Force, but, on the other hand, she
is using the Force. If you put together the OS saying the Nightsisters use the Force with the above, including Filoni's linking of Orphne with Talzin, you get Orphne using the Force. You can try to introduce an unrelated system of "magic" that somehow sits in the same setting together with the Force, but in the end it all comes back to the Force.
