In Elder Scrolls mythology, The aedra became planets. Magnus became the sun.
We have never visited the planets of, for example kynareth.

I have no idea why Kynareth looks like this: http://www.youtube.com/watch?v=FeHExWBxzso
Is there some significance why their shrines look like the way they are? No lore to explain.

Only Nirn (the body of Shor) is playable.

Why can we go to daedric prince's planes (as seen in oblivion), but never to the other planes of the aedra?
What would going to the plane (planet) of Magnus be like? Probably boiling hot like the sun. Or it could be pure magic, as Magnus and other "stars" let in magic to Nirn.

magnus is chillin in atherius i think, the sun is his escape hole back to it. Also the aedra gave up a large part of themselves to create nirn, shor's realm would probably be sovengarde

Hmm... All the other Aedra don't have their own planet? I thought Lorkhan (the missing god) is the only one who gave himself to make Nirn. The other Aedra gave themselves to make the other planets in their name, but we just haven't been able to visit "their" planets yet. So essentially there could be other planets to visit in the future (besides Nirn).

Oh no, they all tore off their limbs to create Nirn. They were all involved in its creation, and thus gave to it. They all have their own planets out there, but astrology of the TES hasn't been by strong suit. I rather liked the idea that they're essentially dead husks of what they once represented.

And there have been a few attempts to reach Aetherius, but all of them ended in failure as far as I'm aware.

So Nirn is the sum of Lorkhan's heart and the arms+legs of the Aedra? The planets would then be the torsos of the Aedra?

Lorkhan's body was torn in two and became the moons, FYI.

I'll admit that I have a lot to figure out in TES cosmology. To throw a wrench into this discussion, how about we figure out what the 12 worlds of creation (that combined to make Nirn?) were. . . previous Kalpas maybe?

I don't think Magnus or the Magne-Ge have planes as we know them.

SHor/Lorkhan is the only Aedra who had died during the creation of Nirn. He had persuaded/tricked the other Aedra to give a part of themselves to create Nirn, weakening them and allowing them to be killable.

Y'ffre is dead too. Every Aedra with a label of "Earthbone" can be considered dead.

It is only a question of how much percentage of an et'Ada died in the creation, aka how much percentage was considered "limbs to build Mundus"

From what I can tell, "death" isn't a concept easily applied to Aedra. Lorkhan is "dead," and at the same time "not dead."

Death to a god is more like sleep, and occasionally become lucid and manifest themselves on the mortal plane.

This I think is probably the more appropriate reasoning, although some part of me hopes that they might actually be able to resurrect, given enough time.

Then parts of Mundus would rip, and not just landmass but concepts.

So how many Aedra are Earthbone? Can you list them?]

I originally thought there were only 8 Aedra (from the 8 divines)
Can anyone list all the Aedra?

Well I meant not as in resurrect by taking back that which they gave but regenerate on their own somehow.

It is 8 plus 1 who are later considered by mortals God-Aedra or Divine or any other norm describing the principle law of the Mundus structure, each law is a piece of Earthbone. The true ancestors of mortals are also Aedra, but weaker so that they have to die in subgradient and are forced to breed to keep existance, aka captured by the cycle of life and death, and these weaker Aedra are no longer considered "God" by modern religions. But of course, by the Psijic Old Ways and Altmeri pantheon we can assume some of these extra-Aedra became several of the Aldmeri ancestor Gods, who may or may not share some link to the Eight God-Aedra. For example Phynaster, Syrabane and Xarxes.

So it is impossible to list all the Aedra, because too many nameless sacrificed themselves into the ancestors of mortals. Maybe some of them are subgradient of subgradient of the eight God-Aedra, but it seems many more are not.

How exactly does Psijic's idea of 11 forces tie together with the Earthbones (if at all)?

Here's an excerpt from http://www.imperial-library.info/content/nu-mantia-intercept mentioning the planets, something I think is worth mentioning:

Auriel-that-is-Akatosh returned to Mundex Arena from his dominion planet, signaling all Aedra to convene at a static meeting that would last outside of aurbic time. His sleek and silver vessel became a spike into the changing earth and the glimmerwinds of its impact warned any spirit that entered aura with it would become recorded-- that by consent of presence their actions here would last of a period unassailable, and would be so whatever might come later to these spirits, even if they rejoined the aether or succumbed willingly or by treachery to a sithite erasure. Thus could the Aedra and their cohorts truly covene in realness.

The popular mortal view is that the Aedra now reside in Aetherius. On the other hand, the Necromancer's Moon, by hiding Arkay from them (I believe the theory is that it eclipses Arkay's dominion planet), allows Black Soul Gems to be made. Personally, I think the implications of that are interesting.

There are "twelve worlds of creation" according to the Anuad, which tells me there were originally 12 Aedra. Though http://uesp.net/wiki/File:OB_Orrery_Planet_Names.jpg only contains 9 outside of Nirn (counting Masser and Secunda as one).

In the Wheel model the Aedric number is 8+1, eight spokes and one hub. Maybe 9 is the number of Ehlnofey-Earthbone, while 3 is something to do with Hist and other mystic existence that are not yet known to us. Or the lost 3 are Magne-Ge, who touched the skin of subgradient and reversing fussion but retreated the last minute?

And the original number of pure Daedra is 12 too. For Magne-Ge we know almost nothing either.

If Anuad mentions 12, then there are 12 Aedra. The 8 divines, Lorkhan (NIrn), Plus 3 more. (if the moons are counted, plus 1 more). Magnus (the sun) probably is this last one.

Lorkhan is the moons, not Nirn. Nirn is made of parts from the 12. And the sun is a hole to Aetherius, it isn't Magnus's plane(t).

I don't think the worlds of creation are equivalent to Aedra. They are mentioned in the Anuad as pre-dating the shattering of Nirn and the separation between Aedra/Daedra/Magna-ge. The association with Hist makes them seem like alternate planes/realities/kalpas.

Or maybe the 12 world are the 12 proto-et'Ada, the 12 world of "I" with both its Anuic-tendency(-future-Aedra/Magen-ge) and its Padomaic-tendency(-future-Daedra)? All 12 failed to CHIM so they had to shatter, until the Dragon-Serpent understand his own Tower and began to create Mundus?

Not quite sure what you're getting at. There were far more et'ada than 12, and Lorkhan was the only one who saw (and purposefully failed at) CHIM. The 12 worlds are mentioned after the creation of the mortal plane, which Lorkhan did not make himself (he was the idea man, Magnus the architect, and everyone else pitched in).

I dug http://daryam.com/monomyth/ up (unfinished, obviously) - it's a comparative timeline of creation.

I thought we already agreed that Lorkhan sacrificed himself to make Nirn? His heart made Nirn. Yeah, perhaps his body made the moons too (can you provide which book it came from?)

So... what are the 12 worlds?
