This is the same pantheon as is described in the 4th Edition Dungeons and Dragons Rules Compendium.
These are the gods and goddesses commonly worshiped by humans, elves, dwarves, gnomes, and halflings, and are primarily good or unaligned in nature.
Avandra (Good) Goddess of change, luck, trade and travel.
Bahamut (Lawful Good) God of justice, honor, nobility and protection.
Corellon (Unaligned) God of arcane magic, spring, beauty and the arts. Revered by the elves.
Erathis (Unaligned) God of civilization, invention, and law.
Ioun (Unaligned) Goddess of knowledge and prophecy.
Kord (Unaligned) God of storms, strength and battle.
Melora (Unaligned) Goddess of wilderness and the sea.
Moradin (Lawful Good) God of creation, artisans, and family. Revered by the dwarves.
Pelor (Good) God of the sun, summer, agriculture and time.
The Raven Queen (Unaligned) Goddess of death, fate, and winter.
Sehanine (Unaligned) Goddess trickery, the moon, love, and autumn.
The evil gods are: Asmodeus, Bane, Gruumsh, Lolth, Tharizdun, Tiamat, Torog, Vecna, and Zehir. There are also a few Primordials that are worshiped by (usually) evil humanoids. More details about these gods will undoubtedly be revealed as the campaign progresses.
In Fallcrest, there is a single temple, where there are shrines to all of the good and unaligned gods listed above. Most people pray to several of the gods, as opposed to revering a single one.
Clerics in this world can be a devotee of a single god, or they can be a servant of the entire pantheon, such as the Keeper of the Temple, Lady Allowen.
