Much like chainsaw man, I just got fitted with one of those stupid starter strings, much unlike chainsaw man, it comes from a lawn mower and I have to take five business days to rev up.
A certain matriarch of the Cleansing Blaze order: “And I took that personally”
Objective proof might be too strong a pair of words, the ages of gods walking amongst mortals have come and gone, and the ravages of time and war have done their work. Much like for magic, there’s only so much information that travels all over the world, which filters through the ever infuriating prisms of culture, biases and ignorance wilful or otherwise.
The nature of divinity is not absolute in the first place, and there are plenty of people who benefit from denying that divinity. There is quite a lot of disdain between certain thaumaturgists and arcanists. Even a display of divine magic may not be enough to be acknowledged in some eyes.
Faith remains the “truest” form of knowledge when it comes to the gods, and objective truths remain ever elusive.
That’s an interesting question. It depends on the time period as well as one’s perspective.
Walls of text lie beyond this point.
It used to be much “easier” to worship evil gods, once upon a time when mortals were puny, weak and utterly at the mercy of the uncompromising ruthlessness of nature. Gods of rage, madness, fear, filth, cruelty, people were ready to turn to anyone who would offer them salvation. And as the people turned their backs to these gods, their wrath, their revenge against mortals took horrendous forms that remain to this day. Though many of these gods have been destroyed by an alliance of “righteous” gods, or so the stories tell.
Some of these old gods are still worshiped in remote, heathen lands, and some are worshiped even as part of pantheons of more “acceptacle” gods. The pantheon of hunting gods Svaltra belongs to also contains such gods as the “Beast of Culling”.
Far in the southern continent, there remain people who worship their lich royalty as gods. Some of these kingdoms were put to the torch by those who considered the practice despicable and these gods evil. Then again many would argue these creatures are not true gods, but deified immortal kings and queens for all the difference it makes to those who worship them in earnest.
Stories travel with Nevarran merchants of lands of gilded abundance in the midst of blasted desert wastes brought about by the wonders of the undead gods.
Perspective does wonder to “make” evil gods as well. The Kriegsvolk’s storm god, Gundhyr, is seen by many as a destroyer and the lord of anarchy and senseless bloodshed. The Nevarran God-Empress of the Sun, Amon, is considered by many as a ruthless and bloody tyrant who crushes anything and anyone underfoot if they so much as dare to show the slightest hint of defiance.
The worshipers of abyssal gods were once more open about their activities, entire countries had dedicated themselves to the whispering gods. But the influence of the gods of the fathomless depths spreads best under the cover of darkness in the end. These kingdoms of the ancient ones were doomed to fail, instead the cultists belong everywhere.
There are many, many gods who were not righteous in any way, but also not evil enough to garner the bad kind of attention. Some of these gods were also too discrete, too insidious to be caught, and in turn not the kind to like the kind of spotlight that political entities bring to them. Baal’raum the god of the savage wilds, Kurrow the god of plague and cure, the elusive god of the jester courts and many more…
Even the most righteous gods could be fickle and cruel, in the end, what you consider an evil god is up to you.
In the end it’s difficult to openly worship evil gods in most places, the Central Continent has proven to be especially self-righteous about culling out “evil” cults. And if a cult is objectively against the interest of most, it’s unlikely to garner much interest, or to live long if it does. Which does not mean they never thrive. In the wastes and in other remote places, under the darkness of civilization, or the empires of less… puritan mortals.
To conclude, the worship of evil gods is usually more personal than communal for all these reasons, and more unlikely to be an inherent part of any political or cultural entity.
