Thinking back on that scene, there's another character that needs split gender lines. And that issue requires another character to be added to the list.
Who wants to be Darth Revan?
The concept behind the line - if you hadn't figured it out already - is that major Sith characters in a vision are asking you to verbally complete the Sith Code.
The one line that I'll need for Revan is "Through power, I gain . . ."
No mask filters and no pitch changes! I need a female version and a male version for this, folks!
Update: Just tweaked Malak's line in the mod. (Yes, he's part of that vision scene too.)
