Medland Pantheon - The Five Civilized Gods
These gods are the official state gods of Medland, owing to their pact with Guldrex, the first emperor. Meniards are officially forbidden from

Medland's hegemony in the region means that these are the most commonly worshipped gods, and the least controversial - no one ever accuses these guys of being demons. You can find shrines to them pretty much everywhere, even in regions that predominantly worship other gods.

The exception is Guldrex, the first emperor of Medland ascended to divinity - he's very much a Mediard-only god, and it's considered weird and vaguely traitorous for foreigners to worship him.

The Enlightenment
The Enlightenment is a non-theistic philosophy adhered to by the Pilgrims. It doesn't reject the existence of the gods per se so much as it rejects their conventional role in mortal life and preaches mortal self-sufficiency and independence. The enlightenment has its origins in Medland, where the original lawgiver lived and preached. However, the enlightenment is far more popular on the western continent; many westerners make a pilgrimage to the lawgiver's original hometown.

Afterlife
Meniards have a special afterlife because of Guldrex's pact.

When all other mortals die, their souls are sent to to the purgatorial land of the dead, from which they must make perilous yearlong journeys to their final resting places, the afterlife planes known as the five heavens and the forty hells.

Most souls seek the five planes of eternal paradise, but the forty gods who reign over the forty hells and their servants are forever trying to trick and mislead pilgrims.

There's no inherent association between an associated heaven/hell and whether a deity is good or evil; the planes were just arbitrarily divided this way by Bosht.

Almost all gods claim that their domain is one of the few heavens, but most are lying. There are a handful of exceptions; followers of Biznthesh, for instance, are perfectly aware that their god's plane of endless bees is commonly considered a "hell", but they think it's actually cool and good.

Souls wandering the land of the dead can be raised with Raise Dead, but souls that have moved on require Resurrection spells or similarly powerful magic.

Excluded from all this are Dwarves, who all go to the Dwarf afterlife which is perfect in every way because Bosht loves them.
