Finish Chapter 1

I can understand, how, as a player you want to be called ma'am. But your character grew up in the star wars universe and per lore would have not heard a female officer referred to as ma'am. Would it be a nice change? Yes. But I ask you to remember that your character may not have ever heard ma'am before.

"While the most common crystals used in the process were from the Adega system, Ilum, and Dantooine (in the so-called "Crystal Cave"), Jedi and Sith used a variety of crystals to produce various colors, effects and unique abilities. Some crystals could even enhance the Force skills of a particular user." Basically both side used many colors. Jedi FAVORED blue/green and sith FAVORED red, but neither were restricted to those colors.
