Anu and Padomay predate both time and other, more familiar deities such as Mara, Stendarr, etc. The interaction of stasis and change produced Aurbis, the universe. Within Aurbis: Oblivion, Aetherius, Mundus, and the Void.
Anu rebirthed its soul to produce Anui-El, everlasting light and the soul of all things. Padomay rebirthed its soul to produce Sithis, the void.
When Anui-El rebirthed as Auri-El (more familiarly: Akatosh) time began, and when Sithis rebirthed as Lorkhan, Sithis’ wish for Lorkhan was to destroy.
Interestingly: Lorkhan’s nature is not one of destruction, but of creation: ‘his’ (Lorkhan is often gendered as male) body compromises Nirn, the planet/plane that Tamriel and all living things, daedra excluded, live on. At the same time, Lorkhan was destroyed so that Nirn could exist, but according to many renditions of creation myths, he 'tricked’ the other Aedra - their energy cost to creat Nirn was so great that they were trapped in Mundus ('the world’, the sphere where both Nirn and the remnants of the creator Aedra dwell) forever, severing them (and their supposed descendants, the mer) from Aetherius.
Auri-El is a deity favored by mer, while Lorkhan is a deity favored by men. Lorkhan is neither Aedra nor Daedra, but something in-between.
All reincarnations are direct opposites of one another, and exert opposite pulls of influence. However, because Lorkhan has 'died’ (effectively disappeared from existence), he is often referred to as “The Missing God” and exerts his influence on Nirn via other, more indirect means, usually agents named “Shezarrines”. Akatosh leads most pantheons as the First God, but does not exclusively aid mer.
Both Akatosh and Lorkhan are the only truly ubiquitous deities that show up in every race’s pantheon.
The Bosmer native to Valenwood worship their own set of deities. It is not uncommon though to see Bosmer worship one, or more, of these Gods. The Pantheon is as followed:
Y'ffre Y'ffre is the God of the Forest and Song. He is the most important God to the Bosmer and was the one who instated the Green Pact between him, Valenwood, and the Bosmer.
Auri-El Auri-El Time Dragon is known as the King of the Gods. he is the son of Anui-El and the soul of Everything. Although Auri-El normally takes the head of most Altmer Pantheons, the Bosmer find Y'ffre to be the god of ‘now’. Is also credited to creating the mortal plain.
Z'en Z'en is the God of toil and the God of payment in kind. He is an agriculture based God and there are very few Bosmer who worship him.
Xarxees Xarxees is the god of Secret knowledge and ancestry. He is said to have been a scribe to Auri-El.
Baan Dar Baan Dar is the God of tricksters and thieves. Worship of Baan Dar is uncommon and he is considered a lesser God compared to others.
Jone & Jode Jone is the Goddess of the Little Moon. Jode is the God of the larger moon, Massar.
Ius Not much is known about Ius, but his worship is seen throughout Valenwood, Elsweyr, and Hammerfell. He is commonly shown as a disfigured humanoid carrying a rod.
Bosmer also worship the more popular Gods Arkay, Mara, and Stendarr from the well known Pantheon of the Nine Divines, and the Daedric Prince Hermaeus Mora.
