Noticing anything? It may just be that Valinor's social environment, and gracious array of distractions, encourages one to think about time less.

It's very subtle or it wouldn't have gotten past me this long. I don't have anything definitive.

And they reach the Máhanaxar. The mountain splits open, here, sheer and stunning on both sides. The thrones of the Valar are bathed in the light of the Trees. They are close enough to the Trees that the light is blinding; the heat would be unbearable, too, if not for the altitude.

Bella squints even behind her tinted glasses, closes her eyes and borrows the companion's.

By Elven eyesight the impression is 'bathed in glory' rather than 'blinding'. Manwë's throne is in the center. Do you want me to go with you? Rúmil asks her.

...If you want. Um, any advice?

Try being polite, and suggesting an improvement that would make Valinor more of a paradise for you rather than a complaint about how it's governed.

By now it's familiar; her skin prickles like the air is full of static, her hair tries to stand on end, the world goes silent around her except for the distant impression of an angelic choir, and Manwë's chosen form is tall and muscular and powerful, a god of the airs who could toss lightning bolts, with a long beard and the eyes of an old man - or they should be, except they're glowing - and he says "Hello, child."

"Hello. Um." aaaaah "I came because I noticed that something's changed about my time sense since I've been here, and I would like to opt out of it and go back to how I used to be about the passage of time, please."

Minutes feel normal, but I spent an entire local Year not noticing that the days were more than twice as long - which could just be the Trees making me need less sleep - nor caring that there were almost five times as many days in a year, which I don't know how it would have happened. It seems like it might be making it easier than it should be for me to put things off and work slowly and linger over things without defined endpoints of which there are many and to consider things that happened years-as-my-plane-counts-them-ago 'recent'. - Although I do like that I can still pretty clearly remember things from my home plane, if there's a way to get the rest of my time sense back without the fading memory.

The things you are describing are properties of Valinor, not things done to any person within it. The Ages leap by here, but not in a way that we could forestall for a single individual. Events feeling recent and memories of them being vivid is a great deal of how time is sensed. You could live outside Valinor, on Tol Eressea, which is safe from dangers but has less of the magic of the continent itself.

...Okay. If you can't fix if I might go do that until I have a ward or a subtle arts trick for it or something.

I could fix the vividness of memories, but that's the thing you do not prefer fixed, if I understand you rightly.

Right. Will they fade right away when I go to Tol Eressea?

Do you desire that?

No.

Then we can ensure that they do not.

Thank you. Will leaving Valinor have any other effects like making me age again or anything?

It seems inappropriate and unwise to have you as the first Man in Arda an Age before they were supposed to arrive. We've been speaking with Eru about changing your fate to that of the immortal Elves, as the simplest approach. It is a grave thing and not done lightly, but if you desire it, you would then not age within Valinor or outside it.

I can't think of any good reason to want to age. Is there some advantage to it I'm unaware of that applies here?

I think it is related to time sense; when there are visible and physical markers of the passage of years it is easier to sense them. It is also said that Men, when they die, leave Arda behind, while the Eldar are as a consequence of their immortality bound to it.

Um, where do Men - go?
