"For what is it to die, but to stand in the sun and melt into the wind?"
Obi-Wan Kenobi saw his death some years before, staring into a Tatooine sunset, from the Anakin he knew: half-broken but still human, not this thing calling himself Darth Vader.
Anakin, with hate burning in his eyes, raising his lightsabre to strike.
It is not how Obi-Wan wanted to die, in the cold sterility of an Imperial warship, but he is ready to meet his death. He can buy the others an escape: theirs is not a task for old men.
Obi-Wan lowers his lightsabre and sees only the sun as he gives himself to the Force.
