Natural enemy idea: ancestor and the darkest dungeon(images 3&4 spoiler for darkest dungeon)
Glad I managed to get this in just before sunday ended
All right, so for those who don’t know who the ancestor is the short answer is he is that meme of local guy ruins everything.
Long answer, he was a high ranking member of nobility who grew tired of the drink the women and the food and decided to delve into occult practices.
This wouldn’t make him a natural enemy, but what he ends up causing definitely does
First off: it should be known that he’s responsible for two kingdom, conquering threats known as the crimson court (bug like vampires without the normal weaknesses) and the witch coven with a fungal army.
This doesn’t also include his creation of the swine by summoning other worldly creatures and putting their bodies into pig corpses, as well as a hoard of skeletons, thanks to his final experiment in necromancy, or that he drew the fish men towards the surface world so he can obtain eldertich knowledge
There was also the time while studying astrology, he summoned what’s equivalent to the color out of space into a farmers field, partly because he didn’t like the guy and wanted to be petty.
But those aren’t why he’s here, oh no, he’s actually responsible for two near world ending events in his series, the first one I should mention is actually from the sequel where it’s revealed he empowered an artifact called the iron crown which someone else almost caused the apocalypse with.
As well as creating more monster factions.
however, even that’s not the reason he’s here that’s just all stuff for the human survivors and other natural enemies to have to deal with while he’s preparing the true threat.
(Warning, the next part, a massive spoiler for the original darkest dungeon)
You see it’s revealed that the darkest dungeon the game is based around is actually a part of a giant eldritch abomination that is essentially the heart of the planet, and that the ancestor has become its herald and all of the death caused in the game was actually meant to be sacrifices to awaken the heart.
The heart itself would be the true natural enemy, as it seems that it’s plans are to absorb humanity itself into it, claiming that they were created by it, as well as possibly crack, the planet itself like its own egg
But as I’ve noted, this thing is technically asleep with its heralds such as the ancestor or the crimson courts countess acting as its envoy to spread death and awaken it.
This of course in the world of verses could be pretty nasty as now we’d have a cult made up of multiple monstrous creatures, and insane humans who have turn to worshiping the heart, knowingly, or unknowingly working together to awaken a world ending eldritch entity.
With possibly each fight, bring the creature closer to awakening, that is unless only human sacrifices count at which point we still have a big problem.
That said the real problem would be most of the people in the setting would know about the true threat line beneath them with the ancestor as the face of what people suspect the natural enemy to be, not knowing what a true horror behind it is.
