Ive Found Wikipedia to be quite informative to a degree you can research gods , dieties , heros , and thats just to name a few ; check it http://en.wikipedia.org/wiki/Moander
Wikipedia
Forgotten Realms wiki is even more informative! http://forgottenrealms.wikia.com/wiki/Moander
look at www.nwnwiki.org
Please keep in mind that our Realmslore section of the forum is based on 3rd Edition rules/sources, and that's how we play here; Wikis and such likely reference 3.5E sources.
Also, there's "some" stuff that's happened in EFU that hasn't happened according to canon timelines, and there are some mechanical concessions we've made just to keep the world spinning.
