The http://www.imperial-library.info/nine_divines/, more commonly known as the 9 divines.
The Nine Divines are not the only Aedra. The Earth Bones are also Aedra, and get here and there worshippped (Jeffre by the Bosmer, for example), and in the end, Men and Mer are descanted from those Aedra who could not retain divine power (using the Merish take on it, but I think it fits).
I'm just waiting for someone to try to connect Sithis with http://en.wikipedia.org/wiki/Differance.
Ohhh, that fits, if I have understood the wiki explanation correctly.
And for the sake of completeness...
Malacath is the only Deadric Prince to join the Daedra since the schism that split the et'Ada.
Meridia?
Someone correct me if I'm getting my lore wrong, but I believe that Trinimac was some sort of demi-god knight working for Auriel (Akatosh) during the Merethic era. He tried to stop the Velothi migration and got eaten by Beothiah for his trouble. He was corrupted, became Malacath, and all his followers became the Orcs.
Actually, there was nothing demi- about him. It has been said he was more revered than Auriel himself at some places.
Also, Malacath may be the only example of actual, factual apotheosis on record. Not sure, though, since he may have been a diety back when he was Trinimac. Most texts, however, seem to treat Trinimac as being less than the Aedra or Daedra. (If Trinimac was a full-fledged diety, his association with Akatosh means that he may have been one of the Aedra. In that case, his movement to the Daedric pantheon is interesting for a different reason.)
Its no apothesis in the classic sense of the word, since he indeed already was a deity - indeed, he didnt ascend, but descend. But TES is choke-full of apotheosis! Just ask Tiber Septim. Of course, they dont always work as planned. For that, ask the Selectives.
So, basically, Anu and Sithis are the equivalent of yin yang or a sort of karma?
One takes, one gives and vice versa to maintain balance?
Yes and No. Anu and
Padomay are the two main forces of the TES universe, and indeed the entire TES universe is just their interplay on various levels (Myth Echos). Theres even a sort of Karma in the Lunar Currency, but that is where things get obscure...
But that doesnt mean theyre Yin and Yang as IRL or as Karma IRL. For example I dont think Anu and Padomay have ever been descriebd as giving and taking forces...
And for the record, as a nitpick on terminology, on the various levels its Anu/Padomay, Anuel/Sithis, Auriel(Akatosh)/Lorkhan, Aedra/Daedra.
