Hello, and thank you!!!

As for your question, ahhh... honestly I don't really have a lot to say lol

From a completely geological perspective, we're told that the Sun World is the only level that gets sunlight.

Meanwhile, we know that the Underworld is frozen and cold - likely because it doesn't get any sunlight whatsoever. And it seems like the Astral World is just constantly submerged in cloud cover.

However, from what we can see, the Astral World is still, at least... visible.

And what I mean by that is -

The top of the Red Line is so far above the clouds that it can't even be seen from below, and rain water can't reach it. It's to the point that Celestial Dragons have a fear of rain because they never have to deal with it.

With the Astral World, we can still see the top of the tree. It's just kinda washed out by the clouds surrounding it.

Until we learn more, I feel like it's just... a place that's constantly covered in fog. Like some sort of celestial swampland.

It's possible that the very top can poke through the clouds and offer a clear view of the sky, but we just don't have enough information to say anything rn

But again, that's from a purely geological perspective of the island based on the information we've been told

There's a very high likelihood that Oda is gonna play around with its design by using Norse mythology - much like the rest of the island. But I'm not well versed in it, and I don't personally know enough about it to suggest what he might try to do
