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.
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?
