Sith lightsaber techniques

Did the sith of any era actually have any specific fighting forms like the jedi's 7 fighting forms ?

I have always wondered, because since some of the sith did not grow up as jedi and their masters didn't either, how could they know the 7 forms of jedi fighting?
for example i am pretty sure the sith of vitiate's empire did not use the 7 forms bc of where they originally came from and how they were the last of their kind , sort of.

Sith Shien, and Juyo are Sith styles, the latter of which the Jedi adopted.

Wookieepedia says that the TFU video game is the source for Sith Shien, but the only other results I have for Sith Shien on Google are fanon wikis and stuff about normal Shien. Could you confirm the source describing Sith Shien?

I believe the SITH of banes line adapted the styles of the Jedi and I'm pretty sure the SITH of old as Malgus is a believed form v and iv specialist.

Remember, the Sith Empire was founded by 12 sith, including their greatest warriors. Ajunta, XoXaan, and so on were their teachers.

So, while there may be some form drift, I would think many of the styles would've been carried over.

Agreed,they have Sith Shien,Juyo ,and Dun Moch.I believe those 12 carried the light saber styles with them. Shii Cho and Makashi,I'm sure.
