Deities of the Nentir Vale:We'll be using the sample pantheon called Dawn War Deities provided on page 10 of the 5th edition Dungeon Master’s Guide.
At the beginning of time, the universe was divided into the Elemental Chaos and the Astral Sea, with the world sitting between at the center of the universe. The gods were the original inhabitants of the astral realm when the world was newly created by the primordials from the untamed Elemental Chaos.

The shared mythology of D&D talks of the Dawn War, a war between the primordials and the gods. The gods fought to stop the primordials from destroying the world. The gods united against the primordials and were able to gain a narrow victory. The primordials were imprisoned, but the threat they present remains.
Today, the home of the gods is the Astral Sea, the former battlefield of the Dawn War. Most of the deities who survived the Dawn War reside in dominions located somewhere in the Astral Sea (though some reside in the Abyss, Shadowfell or even just wander the world or cosmos).
In the Vale, commoners and adventurers will often revere (or pay lip service to) more than one deity, praying to different gods at different times such as Bahamut for protection, Avandra for safe travel or the popular Pelor for fertile crops. Each deity has their own vision of how the world should be, championed by their clerics and paladins. Nice thing about this pantheon is that it can act as a single source of deities for all the major races found in the setting.
The Dawn War pantheon contains gods from a variety of sources:
three unique gods (Ioun, Melora, Torog)
nonhuman deities (Bahamut, Corellon, Gruumsh, Lolth, Moradin, Sehanine and Tiamat)
Greyhawk (Kord, Pelor, Tharizdun, Vecna and Raven Queen which is similar to Wee Jas)
Forgotten Realms (Bane)
Greek (Avandra = Tyche, Erathis = Athena)
Norse (Raven Queen = Hel)
Egyptian (Zehir = Set)
Here is the list of the gods of good, neutrality and malign.
