So you're wanting a Sith Lord master for your character? I would be willing. Here's a sample post.
Darth Malak smiled maliciously as his master turned his back on him. Jumping suddenly, his lightsaber in hand, already springing to life, he attacked. Revan's force instincts allowed him to deflect the attack. "Malak," he gasped. "What are you doing!?"
"It's simple, my master. It is what all sith do. They become more powerful than their masters and turn on them. I have grown much stronger than you, as you just admitted. So, I am now going to--" He paused and a menacing look appeared on his face, "Destroy you."
That's not my best, not by far, but it's late and I'm rushed as i have to get to bed soon! :P Anyway, I'd be happy to help yuo out as a master!
