Leia. Han. This letter is for your eyes and only your eyes.
You both know I never meant to turn. My intentions were never dark and the only side I leaned towards was the light.
However I have felt a calling, a calling to the dark side. The dark forces seduced me after the death of my, our, father.
The darkness makes me strong, it gives me power and control. It gives me what I seek in life and fills the emptiness created by never having a family.
The darkness has changed me, made me worse for the better. It has opened my eyes into seeing what really matters.
I now see the path that I need to follow, and the destiny I need to fulfill.
No longer will I train in the ways of a Jedi Master, but I shall learn the ways of a Sith Lord.
I ask you not to stop me, do not attempt to disrupt my training. This is for your own safety. The darkness has and will only make me stronger.
This is my letter goodbye, not only for you but for myself.
I am gone.
Do not try to save me now.
Sincerely,
Luke.

The letter had appeared on her night stand over night, she did not know how it got there or who delivered it, all she knew was that it wasn't meant for her. Her name wasn't Leia, and it definitely wasn't Han, and the letter was not meant for her eyes yet she read it anyway. She read each word carefully, slowly, and with extreme precision. She poured over the letter over and over again, unable to stop reading the words. Each time she read the letter she became more and more heartbroken, more and more scared, and more and more confused. She did not know any of these people, Han, Leia, or Luke. She had heard their names before, thrown around local pubs or murmured on the streets. She knew who they were, they were the trio who destroyed the Empire, but she didn't know what this letter meant.

She was never educated on much when she was young. She didn't know what the force was, what being a Jedi or a Sith meant, she didn't even know if all that was real. She liked to imagine but keep to herself, she never tried to act. She did what she was supposed to. She didn't interfere in anyone else's business. Reading that letter definitely wasn't her business. It was the business of only two other people in the entire galaxy, and that was the Han and Leia that Luke spoke of in the letter.

She knew that this letter was of great importance, some way, some how, she knew. She also knew exactly what she had to do next. She knew that she had to get that letter to Han and Leia.
