http://www.gamesas.com/bgsforums/index.php?showtopic=864578 is the page over at the modding forums, please read it for a full detailed explanation.
What I would like is any helpful advice for lore buffs, some tips on how things should go etc.

I especially need some help in researching the ancient Ayleids.

If you read the outline, you can see that one of the groups is searching tirelessly for Ayleid secrets, and I need to know a little more than I do about this, and I want some opinions, because people in game need opinions too.

Keep in mind it is important to the spirit of this project that not everything be explained away in much detail. This mod must purposely leave a lot for conjecture, and allow the player to have some imagination. And everything is wrapped in an aura of mystery.

Also, lore wise what would be good names for:
The Hidden Order
It's rival order (who now wants to find out all about the ayleids, but used to be very anti-ayleid)
Several ayleid cities that now are order and rival bases
The Tome spoken of in the outline

And beyond that, any thoughts or advice are greatly appreciated (unless they are unnecesarrilly crual or mean)

Thanks all!

Another thought that if possible could come into play at least in order lore/history. Is there or theoretically can there be such a thing as a Shezzarine, due to Shezzar's current state?
My thought would be that the answer is kind of, there can be a semi-Shezzarine, but since he lacks his heart for various reason, he's not all there.

The Hidden Order: The Nine's Crusaders(?)

Rival Order: The Order of Foreign Magicka (?)

Cities: Vilenia, Xersus, Vilvama.

Sorry if it's not 100% lore, I have just started getting into Lore

Well, thank you for your response. I will certainly keep them in mind.
