What does decay have to do with it? Or excess time?

Paper doesn't rot. And it takes a long time to scribe books and things. Most Elves outside Valinor didn't even live in the same place for long.

Paper rots here, and we still used writing even before we had ways to do it faster than hand-scribing everything, but the nomadic lifestyle would certainly make it less appealing.

And the dark.

How do you have a forest in the dark?

Yavanna. Vala of trees.

And she grows trees. In the dark. ...What is even the point of the 'tree' design in the dark.

Fractals are pretty. They don't look much like trees look now that we have a Sun.

You just... started having a sun.

The Valar realized that the planet being so dark was a problem so they built one. 

Your world is weird.

Your world has a Sun too!

Yes, and it predates the planets by I think billions of years!

Well, the Valar forgot to do the Sun first! But now we've got one.

Why does your species even have eyes if it was constantly dark all the time everywhere. Animals that live in caves or the bottom of the sea don't bother with vision like that.

You could still see heat. I think Elves mostly see heat and light is like a bonus.

Humans cannot see heat.

I'm sorry. Want to osanwe my vision so you can tell the difference?

You can do that? Sure.

So she clumsily tries to throw her vision to Bella. She's shared it before but not with anyone who didn't themselves have osanwe.

...wow. You see a lot better than humans do. A lot.

I'm sorry. Vision's pretty great. I'm also not an Elf, but mine is comparable to theirs as far as I know.

I might be able to use magic to sharpen mine up like that, I'm not sure if it'd cost to sustain or just to do.

Oooh. If it's just to do, even if it's a lot to do, that'd be great. Could you give yourself our strength, too? 

I got a strength boost just as part of baseline puella magi powers, but I could boost it more; that's a cost-to-sustain though because it's directly applying force with magic, not re-biologizing myself.
