In the midst of his endless walk to find someone, anyone that is alive, the being collapse, feeling a strange sense of exhaustion for the first time. He has traveled far and wide across land, sea, sky, space, and time. Now, the world is barren of all life, and the being can feel something rising out of his body.
Is this...death? The being thought.
The being thought back to the first life-form he met, too microscopic to even comprehend its own existence. He thought about the next life-form that fascinated him: a group of creatures that not only give him various names, but even worship him. Finally, the being thought about all the senseless slaughter that lead each life-form to a weakened state, where he gets to the last members of the race before they leave.
Their souls would transcend across boundaries and enter the afterlife. The being thought. But, what about us, what happens to us after we die, when no one is left to remember us anymore.
Pondering that question, the being slowly loses all thoughts. And thus, even Death has met his end, and the world falls into complete silence.
