These are the main gods of the Empire, both good and evil; they allied against demonkind but squabble and fight each other sometimes.
Many mortals have ascended to Sainthood, either of the Light or the Dark. Most of them are only relevant to people living in specific cities or doing specific occupations; just about any occupation which has been around more than the current age has a Saint. Every saint is linked to a god or goddess, though sometimes it may be hard today to understand the link. A few of note are listed below.
Barbarians worship some of the same gods as the Empire and some different ones as well. They also view some gods differently. Many humanoids worship this pantheon, just under different names. The heart of the pantheon is the ideas of strength and rewarding service generously. The Free Folk see themselves as free of the stifling laws and corruption of the Empire, which they see as evil. Only the Gods of the Peoples are truly worshipped; evil criminals and spies worship the Imperial Gods, though at certain times of the year, they are appeased with special ceremonies. Many Barbarians also practice some degree of druidic practice.
The Serpent People worshipped different, alien gods. No one worships them now but they are thought to seek to revive their Serpent children and probably the Yuan-ti DO worship them. They will not bow to Bane, so they are not part of the Dark Gods officially; they are pretty dark in practice.
Various past incidents have brought gods from other lands to ours. Not all of them are worshipped legally in the Empire, and those that are still are seen as… weird.
