I remember reading somewhere that Skyrim would have it's own proper luna cycles. Is this noticeable and does it have any kind of impact? For example; on a night with a full moon is the landscape more brightly lit than a night with a half moon? Does this change anything in the game or is it purely for the "oh wow, that's pretty" factor?

There's one thing that i know:
"Each hundreds of years,the Moon in skyrim become Blood,this time the Werewolfs freely roams around skyrim.But, Hircine the Lord of Hunt,create for himself an Avatar and begain it's hunt"
This was an Dlc from Bloodmoon.Wich the main character kills Hircine Avatar on that time.But unfortunaly i forgot the name of the island.

The moons change night to night, waxing and waning like they should. Other then being pretty and adding atmosphere and believability to the world i know of no actual impact thus has.

More Ow wow that pretty than anything me feels. I DO notice, and maybe its my configuration or imagination lol but I do notice that the landscape takes the color of the Sky from Aurora's I've yet to see a FULL Masser and NEW Secunda so I can't comment


damn peeps should really look at the Aurora's more, they are Tear jerkingly awesome.

Indeed, it is noticeable.

Full moons are equally as beautiful.

Solstheim, my friend.

Thanks.

If you explore the plains of Whiterun you will find something related to the moons.

And what might that be?

There is a forge that can make enchanted weapons that receive power from the moons.

That's a million dollar question.

Cheers

The wiki disagrees with you.

Not really. There is something related to the moon phases there.

The moons annoy me. They can't seem to agree on where the sun is, with each being lit from a completely different direction.

Explain yourself please.

Indeed. The moonlight at night also appears to still have nothing to do with the positions of the moons.

The 'sun' in TES is a hole from Autherius to Mundus, it is the source of magic. The moons most likely 'produce' they're own glow.
(^just a guess)
(if theres some good lore on it - point me to it, since I'd like to know more about the astronomy of TES)

What are Masser and Secunda?

Masser and Secunda ('Jone' and 'Jode' in the Ehlnofex), the moons of Nirn, are the attendant spirits of the mortal plane. They are like the mortal plane in that they are temporal and subject to the bounds of mortality; in fact of this, the moons are dead and died long ago. The moons used to be pure white and featureless, but today their 'skin' is decaying and withering away. Their planes are likewise dying. Mortals perceive this as the moons being spheres with patches of their 'surfaces' completely eaten away; as the moons spin, they seem to become slivers or ragged crescents. These are not caused by shadows, because you can see stars through the black patches of the lunar spheres.

What is the sun?

Magnus is the sun, the largest hole in Oblivion, and the gateway to magic. Magnus was present at the creation of the mortal plane, and, in fact, was its architect (Lorkhan was its advocate and inspiration). Prehistoric (before ME2500, startyear) Nirn was a magical place, and highly unstable to the first mortals. Magnus then left, some say in disgust, and Oblivion filled in the void with the Void. His escape was not easy, and tatters of Magnus remain in the firmament as stars.
What is the sky?

The sky is another visual phenomenon caused by mortal mental stress, the night sky in particular. The sky is as impossible as planets; in essence, when you look into the sky, 'you look outside the material plane'. At night, Nirn is surrounded by Oblivion. The day sky is the multicolored elemental cloak of Magnus the sun. It changes colors as elemental influences rise and fall. Thus, when one looks at the day sky, they see into the raiments of Aetherius, and stare at magic.
