Sith between the wars?

So, we know that some time following the Mandalorian Wars, Revan and Malak declared themselves Dark Lords of the Sith. They built a new Sith Order when presumably no Sith remained after the end of the Great Sith War.

Then, following the deatsh of Scion, Nihilus, and Traya, there are no records of any Sith until around 2,000 BBY, when a fallen Jedi Master rebuilt another new Sith Order from scratch.

My question is: did Revan and Ruin pretty much rebuild the Sith Order from the bottom up, or did any Sith survive the Great/Old Sith Wars to keep the traditions alive?

And if Revan and Ruin truly did have no pre-existing Sith to help them rebuild the Order, then why is everyone so adament in saying that Lumiya couldn't possibly be a Sith? I'm sure eevryone said the same about Ruin, and look what he was able to accomplish.

 

According to the NEC, Sith survived to continue the traditions.

 

But it's also been admitted that that part of the NEC is erroneous because Dan Wallace didn't know at the time that Kreia and Traya were the same person.

 

Still tracks, since -- obviously -- there would have been other Sith survivors hiding away throughout the galaxy, and enough of them to keep things alive and kicking, even if no major known Dark Lords arose in public sight prior to Ruin's time.

Simply a (happy?) coincidence.

Lumiya is every bit the consummate, legitimate Sith that Darth Ruin was, considering both were utterly bereft of greater guidance and support for a time (Ruin before the founding, Lumiya after Vader and Sidious's deaths), with Shira likewise communing with the ancient Sith spirits on Ziost. Anointment presumably followed, along with refreshments.

Revan, at least, had the immediate skid-greasing of Exar Kun to thank for his re-energizing of the order, very recently done, and with "true" Dark Lords already in existence, to boot. Lumiya and Ruin had far, far less to work with.

 

Actually I wouldn´t put Lumiya so "alone"

I mean, she actually meet two siths and more or less studied first hand some stuff.

 

Yeah, Nemuro's right.

At least in part.

She can't have received formal Sith training, though the Hands and other adepts were given some insights, some limited studies. Lumiya seemed to have been groomed to be Vader's apprentice once Palpatine fell.

 

True...she was more trained than most.
Lets not rule out the help of some long forgotten force ghost, it happens often. And their are certainly plenty of holocrons left out and about the universe. Who knows what hole shes been in for the last half centuary.

 

Guys, that's why I included the whole "Lumiya after Vader and Sidious's deaths" bit...

Yup, which undoubtedly happened during her Vader-mandated sojourn in Sith Empire space, which is where she was when both Dark Lords got it at Endor. Afterward, for the next 30-plus years...we've got nine books coming to fill in those holes. Very likely there would've been occasional communiqués from the old-school Dark Lords during those decades.
