He is old. Very old. If you asked him how old he was... he might say 'as old as my tongue and a little older than my wand'. Which is slightly annoying. But this man is one of the best known in the world – that is, the wizarding world.
The old man sits down. He closes his eyes. He knows his time is near.
He has led a good life. One with many great adventures. But also many losses, many tragedies. Many times those eyes have shed tears... many times that mouth has cried out in pain.
He has done all he needed to. But not all he wanted to. And some of what he needed to do he didn't want to do. There are many things he wished he'd done while he had the chance to. But now he never will.
Because now he know his time has come. Now is the time that he will greet death like an old friend. And as he dies, he shall give Death back his most treasured possession, because it is Death to whom it truly belongs.
He has no-one else to give it to. All he grew up with died long, long ago. He has family, sure, but they are far away, and wouldn't want this. Not this. Not after all the trouble it has caused him.
Still, this cloak has been of great use to him. Kept secrets. Found some out. Saved lives, perhaps. But only perhaps. He fears it will do no good if left in the world.
He opens his eyes to take one last look at the world around him. One last glimpse of the world that he has loved, saved, and at times, hated for its cruelty. But now it is goodbye. He wonders how many people will notice he has gone. And how long it will take them to notice.
But now, he closes his eyes, and they do not open again. And that was the end of the greatest wizard of all time.
