With the Darth Vader comic shaping up to give us some info on the pre-Bane Sith, I noticed that Momin was always referenced to as "Lord", never Darth. In Legends, the Darth title seems to have originated with Vitiate's Sith Empire, as none of the previous Sith and their decendents (Ragnos, Sadow, Nadd, or Exar Kun) (though Andeddu could mess with that idea). In canon, the oldest one mentioned is Darth Atrius from the Star Wars Annual 4. Is there a distinction between a Sith Lord and a Darth? Was it in common in the old Sith Empire? And since this part of canon history is still undefined, what changes would you like to see compared with the Legends continuity?
