Darth Traya - Tumblr Posts
Darth Revan: uses mandalorian mask;
Darth Malak: has a replacement jaw that covers part of his face;
Darth Vader: uses life support mask;
Darth Nihilus: uses mask;
Darth Sion: his face is so disfigured you can't tell what his real face was like;
Darth Sidius: his face is so disfigured you can't tell his real face was like, and before that he used deceit to mask himself;
Darth Traya: used lies and betrayal to mask herself and her objective until the end.
Every sith wears a mask to hide their true, hurt and scared self: it represents their lies, the way they refuse to acknowledge themselves and how they hide their "weakness" and shame.
I can't put in words how much I love this detail and how it contrast with the Jedi who always have their faces out in the open.
In my oponion both characters with the similar goals overall. Thing they want is to destroy the opressing powers(Force, bending) and end the pointless wars.
