Day Zero, the Gods and others.

Skyelund has four main religious regions.

To the north spiritualism and the druids that venerate them hold sway. Theirs is a ad hoc religion, which changes rapidly between the tribes that litter the land. In some places vicious animal totems drive their factions to raid and plunder while in other regions are peaceful and just. Druids who seek to maintain the balance across the lands rather than just within their communities are known as Sentinels and are both feared and respected. Druid.

The coastal kingdoms follow the god Kord, The Storm God, God of Strength and Courage. This leads to conflict within the kingdoms as it's priest urge the nobles to out do each other, however Kord is also the god of honesty therefore the actions of the armies of knights are guided by strict noble codes. Priest of Kord strive to show their strength, determination and spirit. Wandering warpriests, know as Truthsayers, act as judges both in competitions and in law matters. Warpriest (Storm)

The Empire Of The Sun, which occupies central and eastern Skyelund worship Pelor as state deity. Pelor is the Sun God, Light Of The World and All-father Of Man. The empire depends on Pelor's All-father status to hang is conquering nature on, believing that all men deserve to live in Pelor's light whether they want to or not.  However Pelor's role as the soul shepherd means that those clerics of a more martial bent are sent out to defend the living from the walking dead. Paladin Cavaliers of Pelor are the brightest knights of the empire and their holiness is renowned throughout the world. Warpriest (Sun), Paladin Cavalier

To the south in the Jungle borderlands the noble Lesotha people worship Death without name. They believe that only in death do the gods have hold over the people and so do not allow their priest to interfere in politics. However they greatly venerate their dead so the priests are venerated in other ways, despite seeming to work in the shadows. Warpriests of Death seek to counter the evil the seeps into the world from the Shadowfell. Warpriest (Death)

There are other gods. Secretive hidden beings that work behind the scenes and rarely for the good of mankind. Those who study religion will know of the whisperer, a god of secrets and the Night goddess. The most fallen and wicked worship demons, Demogorgon prince of destruction and Orcus lord of the undead being the most infamous. It's also said that to the east other gods and even devils are venerated. Once other things walked the lands and their gods leave shadows too.
