Doodling some more mythic timelines in my setting which is always fun and I can always claim any version is just one school of thought and revise again and again. I used to have a very complex mythology in my 90s games which was nice for RPGing and had years of work. In my present era of DnD since 2012 I have been very loosey goosey on the subject often using Babylonian gods mostly as I know them well just change names and reskin. It worked fine for years but was rigidly weird and I'm in favour of something simpler and less complex. I don't mind heaps of petty bad guys or lots of irrelevant minor gods but about a dozen main popular gods are enough. These will be for my Shadel Port, Exile Islands, and the Fallen Third Empires Knightlands.
I've always liked the tension in say Gygax games was St Cuthbert vs the Old Religion in Homlet setting up a conflict with druids and clerics. Possibly you could do something like this with a Roman type ancient setting where rural peoples gods might have been different or even druidic.
Spirits of the Void
These old spirits lived in the void for aeons until some formed elements, then great ancestral dragons and titans appeared. Fish, worms, bugs and amphibians ruled. Many of these spirits gained purpose as the world developed and changed into beasts or land spirits or dragons.
I am making my older pantheon now distant Titans who just don't interact with mortals anymore and their time was over by the time the world was finished and operational. They had a feud over law and chaos at some point which accelerated creation to the start of the Dawn age on the mortal world.
The First Gods
These children of titans revolted from their parents then feuded among each other bringing ruin to the world and inviting in the gods of the outer void and the great darkness.
The Elder Evils
This followed by an age of evil that spawned most of the surviving evil cults we know today. The age of monsters and darkness brought forth a proliferation of horrid gods and demons and things from the elder darkness. Rebel spirits grabbed leftover fragments of creation as territories and became demons. Ancient beings from the primordial darkness or even things from beyond the void came to crawl into the mortal world. Evil elemental cults thrived and waged war but failed and their strange ideologies crushed.
The Ancient Gods
After the darkness and time as we know it began proper, there was an age of worship of new gods helping humanity overcome the old evils. All the modern alignments as we knew them were established by this time. These are the ancient gods and nature worship that has fallen out of vogue in the most advanced kingdoms.
Since the world recovered from the dark age great nature spirits and heroic rebel ancestors became tribal and city patrons. Some of these gods became related forming extended clans or pantheons who supported empires and acted as any royalty would with scandals and conflict.
The New Gods
In the current modern age with miracles like gunpowder, trade and exploration across the world, printing press many old gods are increasingly irrelevant. The current most popular new gods might just be new avatars of old ones. They freely change their gender, age and cultural effects at will. They can appear simultaneously as male and female or other arrangements with multiple bodies. They are not dedicated to elementals and they may have sects that vary in alignment and behaviour. These gods are under a thousand years old and in some places are normal but in most frontier, wilderness areas they are not. In rural areas, they frown on older cults and sometimes cause them of being evil cults. They are depicted as human mostly with the contemporary noble dress. They are gods for modern occupations and adventurers and less connected to elements or nature than older gods. They are more nebulous and inconsistent in basic appearances when they make an avatar to appear before humans. These gods are still young and fresh and meddling in world affairs and spreading.
Elves, dwarves and others prefer the millions of spirits or thousands of petty gods or ancient gods or titans to the current favourite human gods. Shadelport has over 10 000 registered shrines to various gods. These popular new gods are about 10%.
Will think through some other distinctions of the new gods other ways they differ from older gods.
