Of course, better way to investigate such things - playing the game; but unfortunately it will take too many time I don't have at moment.
So I looked in game resources, but I don't think this method can be considered as full investigation.
I found this list, with Eight Aedra and most likely Baan Dar, but there also six less known dieties.

- Arkay - God of Birth and Death
- Zenithar - God of Work and Commerce
- Notorgo - Messenger God
- Mara - Goddess of Love
- Shandar - God of War

- Dibella - Goddess of Beauty
- Jephre - the Storyteller
- Vigryl - God of the Sea
- Q'Olwen - (wisdom?)
- Stendarr - God of Mercy
- Ephen - God of the Wild
Never saw this in-game, is there something like this? In which conditions can this names be displayed?
Also I found list of different shrines of Illiak Bay. Later I saw this list on UESP, but there nothing useful besides description of generic shrine.

What is the purpose of this shrines? Which advantages they provide? Are they all appear the same?
- Raen, God of Agriculture, his shrine is Reliquary of Raen. Mentoned in "King Edward", fragment a bit unclear to me, but he seems to be Springseed, "handsome blond man, greenclad, with a bow".
- Bandi. I didn't find anything except that his shrine is Shrine of Bandi.
- Mai. The same thing - his shrine is Shrine of Mai.
- Phen - Ephen? Or just a similar name?
- Ebonarm. The God of War. Described in "The Ebon Arm", mentoned in "King Edward", very popular diety in the Illiak Bay and on this forums . He is more or less understandable.
- I'ric. Described in "King Edward" as ArchMagister of the Crystal Tower. Hmm, similar position as Syrabane or Phynaster - Hero, Mage, Ancestor-God?
- Divad. Famous Divad the Singer, Hoon Ding?
- Jone, Little Moon God, also have shrine in Illiak Bay.
- Jephre, the Storyteller, described in "Of Jephre". Is he Y'ffre? Seems that he is.
- Sai, god of Luck, perfectly described in "King Edward". His shrine is Reliquary of Sai.
- Vigryl, seems to be one of seldom Gods, connected to the Sea. Is he the same as Vir Gil, who briefly mentoned in "King Edward"?
- Dugrod - didn't find any information.
- Jhim Sei - mentoned is "King Edward" aloneside with Jeh Free in context of singing and playing.
- Sage (Sage Monument). Is he the Sage, hero of the book with same name, the great wizard Gyron Vardengroet?
- Jode. Big Moon God. Moon gods are subject of another topic, I think .
- Q'Olwen. The odd "(wisdom?)" is all I've got.
- Ephen, God of the Wild, seems to be Moraelyn's brother, S'ephen; Moraelyn established a temple cult in his memory. As in "King Edward" "His godhood is between him and his worshippers". Also mentoned in "The Real Barenziah".
- Strenner - who is it?
- Kieran with his Theatre - hero of "A Tale of Kieran". The culture-hero bard, ancestor?
- Djen (Djen Lodge) - the same as Dugrod, Mai and Bandi.
- Notorgo, Messenger God. Briefly mentoned in "King Edward", and in the names of number of spells. "Feet of Notorgo" spell exist even in Morrowind and fortifies speed. God-hero, ancestor?
- Shandar, God of War (?). His story told in "Mara's Tear", but it makes no sense that he is God of War. This position occupied by Ebonarm, moreover. Maybe there is a mistake? In "Varieties of Faith" written "Stendarr's Sorrow" instead of "Shandar's Sorrow", so maybe it is one diety. One can also compare Shandar and Shezzar, hmm.
