Pretty simple question. Where do you get different lightsaber crystals to change the color of your lightsaber? And what colors can you get? I'm a Sith Sorcerer, if that would limit my selection.

Thanks! Got them both.

I just got to level 10, made an assassin, but I'm not sure what to do about a couple vital things. 1. Where can I find a double bladed lightsber? 2. How do I use my talent points? It says I have 1, but I click on the top talent and it doesn't do anything. Thanks for any help!
