A/N: This is just a little drabble on Obi-Wan I made a while back. It was originally going to be a longer fanfic with other characters, but I decided to leave it at this. Enjoy!
The aging ginger stared out into the bare deserts of Tatooine, watching as the first of the planet's two suns leaned down to kiss the horizon. One was painted red, the other a light orange, but the latter was slowly changing to match the first's color as it neared the horizon as well. A gentle breeze whipped past, blowing the old Jedi's robes out behind him and brushing his hair back from his sweaty forehead. Sand kicked up onto his boots.
Obi-Wan Kenobi's fingers tapped, absent-minded, at his sleeves as he stood there with his arms crossed. How many times had this exact scene played out before? Far too many to count, for sure. He had done this several times over the past few years. Watching, feeling, thinking... So many times had he done this, but, oh, how he could do it forever. There never seemed to be enough time to think, even if it was all Obi-Wan did now.
He watched the sunset, felt the heat and soft breeze that still did not seem to cool the planet in the slightest, and thought... Thought about all of his life. He thought about growing up as a Padawan and being trained by his master, Qui-Gon Jinn. Obi-Wan thought about the day Darth Maul had slain that man whom he cared for so much like a father, and he thought about all the people he had seen killed in the Clone Wars and over the years. He remembered the friends and fellow Jedi he had lost in Order 66.
But most of all, Obi-Wan thought about that young boy he had met on Tatooine so many years ago. The little slave who had shaken his hand so eagerly when they first saw each other on this very planet. The child he had trained and watched grow into a man. His Padawan, his partner, his best friend, his brother... Who was gone. Consumed by darkness.
And it's your fault. The thought went through Obi-Wan's mind without a moment of hesitation. He trembled, grip tightening on his sleeve. He was quite familiar with this knowledge, but every time it came back to the Jedi, it troubled him deeply. Why wouldn't it? He should have known he could never train someone as well as Qui-Gon or Yoda...
You could have saved him. Had you only paid more attention to the fact that maybe Anakin was being tempted by the Dark Side so strongly, he might not have been lost to Sidious... To Vader. This is your fault and yours alone. You didn't even try to save him, did you? No. And now he's gone. All because of you. The voice continued to echo in his head, and as darkness filled the space around him, those dark thoughts seemed to fill the space in his mind.
Lips pursed and a broken expression on his face, Obi-Wan whispered into the night air, "I know it is."
