"I design Ardas by imagining what the most beautiful possible world would be like, and then finding critical moments and doing - detail work? so they will happen exactly the right way, and then creating peoples who will fit into the pieces between the detail work so that everything works out perfectly. It takes unfathomable amounts of time and attention but when it's done it's so unimaginably beautiful and then I set it into motion and the Valar go to live and work in it. They can see enough that the beautiful moments will all be there, but they muddle some details. It's okay because them being fallible servants of my will works better than them being perfect at it - if they were perfect at it people'd be more upset about them letting Melkor out. They might lose faith in me and enduring faith in me is so beautiful.
I see when I start a world if someone will land on it. I let them, if they can make the story more beautiful - sometimes they can, even though I designed it for beauty, because unlooked-for hope has its own beauty. I put them back or send them somewhere else if they're not going to make the story more beautiful.
I like the Arda you call Elentári a lot! It's lovely. It will definitely have more tragedies play out eventually, but I space them, usually, by thousands of years to give some breathing room, so they shouldn't come to pass any time that seems soon to you, and they might be quiet tragedies that escape your notice entirely.
When the Valar consult me I tell them the truth but the parts of it that make the beautiful bits shine the brightest.
They're not the same at all! No two of them have turned out the same, have they. But anyway, the most beautiful story isn't less beautiful for the retelling! Retelling is beautiful!
I haven't tried interacting with adjacency. I think if I wanted to pull someone into an Arda who wasn't nearby, and I knew enough about them, I could do it no matter where they were. I could put all your worlds next to each other, probably, but that'd make everything dull faster and then I'd get bored and then I'd introduce some beautiful things.
I can restrict the degree to which I am omnipotent? For example, I can't know the contents of your mind, because I decided not to be able to, because it would make you less beautiful if I did and you knew it, and it's aesthetically wrong for things to be beautiful only out of ignorance of me. But if I'm not deliberately being unable to do something then I can do it. - if you wanted to send a traumatized Maitimo back in time I could definitely do that, it sounds like an amazing story!!
Bells make for beautiful stories, obviously. There are other people who could do it but Bells when they're around are very suited.
Ardas aren't adjacent because it would inhibit both Erus creatively. It's hard to say 'we move them' because it's not really moving - we just decide that they aren't adjacent, before there's anything to be adjacent - there are so many Ardas, Ardas are so beautiful, they're distributed through the multiverse like stars in the night sky..."
