I don't get it. What's up with sith names? When sith inquisitor becomes member of the dark council, he gets the name of Nox/Occulus/Imperius, yet the sith warrior does not, despite being dark lord of sith as well.
Darth Baras had his sith name despite being lord of sith, not darth, and he did not change his name after joining the Council or becoming the dark lord, yet Darth Thanaton had to become dark lord of sith to get his.
WHEN does sith get his 'special' name, after all?
from what I see in SWTOR it depends on individual, his preferences/position/status among the Siths. Inquisitor was just a mere Lord who gained power and so Dark Council named him. Wrath on the other hand is above them and they would not dare name him like one of their own dogs - he is a Wrath, whenether Darth or Lord, it doesnt matter much as he is above those titles so it is up to his preferences - even Sith Emperor didnt call himself a "Darth" but a Lord, Lord Vitiate and who would stop him for naming himself a Darth.
