Premier (S.I.D)

The title of Premier was a rank and title (yes, I'm being redundant, come at me.) similar to the title of 'Emperor' or 'King'. It was considered to outrank everyone else (Well, except obscure groups like the Sith Society, Sith High Society and Sith High Inner Circle)

It wasn't used that much due to the fact it was an obscure rank and every failed Sith government used the title 'Emperor' (The Sith Imperial Dominion are taking steps in the right dimension, small, baby steps.)
