Organised religion isn’t an especially powerful force in Nimressan society. There is an acknowledgement that there are powerful forces that are best respected, especially Nature herself, and other, lesser powers who might appreciate one’s respect enough to grant certain favours… but religion certainly isn’t the foundation of a moral code, or the key defining trait of a person or community.
The Fey Powers
Although the Arch Fey have been legends for longer than recorded history can countenance, they are still revered. There are festivals held to all of them, throughout the year, and sites sacred to all of them near their reputed homes.
They have no priests. Rather, acts of worship tend to be civic, community wide events, with community leaders responsible for organising (though not always funding them). The festivals are part celebration – many of the Arch Fey are (mis)remembered as noble, kindly, and peaceful – like the Lady of Roses – and part placation: even if they’re remembered fondly, there’s a general agreement that Nimressa is better off without powerful, incomprehensible beings holding dominion over it.
The Age of Legend gave birth to many heroes, who are remembered (accurately or not) to this day. Although there’s a broad consensus on their names and identities, they’re remembered for different deeds, and honoured in different aspects, in different locations throughout Nimressa. In Baford for example, Carida the Harpist is known as a singer with a voice that could lull the unquiet dead to sleep; in other regions she’s known as a silver tongued liar, or even a poisoner.
Practices are more centred around ‘honouring the dead’ than specifically worshipping. But they do have clerics and paladins, because these powers actively listen… and apparently like being honoured, respected and remembered, and respond with blessings and miracles.
Nature is by far the most powerful force in Nimressa – a realm of majestic works of nature, from great, ancient forests, to rumbling volcanoes and snow covered mountains. Most people agree that you’d have to be an idiot not to make some gesture of respect towards it. For the average person, this just means an assortment of gestures.
It also means that those with the ability to shape and guide Nature – Druids – are revered themselves. One does not casually anger a druid, for example, nor even disrespect one.
