Do you have some advice on how to evoke feeling of harshness in the setting without making it caricaturally grim or simply stingy with resources? Something like tolkienesque First Era Beleriand with inaccessible gods and great danger nearby but with less superpowered elves and less focus on nobility?
I tend to be sceptical about unrelenting grimness—because I try to make my game world logical.
“The world has been enveloped by a fog of doom for a hundred years”. Okay, all people are dead from starvation. The last cannibals died decades ago. Next world!
The world has to be—has to be—sufficiently benign that children will, on the whole, survive into adulthood. Think about the hazards you put into your world. A 10% chance of killing each inhabitant each year? The population is now plummeting.
I think the way to evoke the setting you want is to have good areas and bad areas, benign conditions and crises. It’s the contrast between the two that’ll evoke the feeling you want. Happy kids, educated populations, active trade and thriving farms will just serve to highlight how grim things get when the systems of society break down.
A war, plague, fire or flood, a bad ruler, a subversive cult, or a band of wandering murder hobos become unutterably grotesque when your characters see its effects on ordinary people.
Are you looking to make a setting with the Good People being in a long term war against a Dark Lord and its armies?
I think making the evil armies consist of people who are either willing or at least compliant to erase whole countries even though they have the capacity to refuse or resists would be a much stronger start than the enemies just being monsters who are not able to behave any differently. They could even just be humans. There have been millions of people who have enthusiastically participated in such campaigns of annihilation all throughout history. No supernatural influence needed to make them do it.
I wanted to make a setting with somewhat powerful PCs, heroes of the land, but at the same time give players the feeling they need to be that powerful because the world around is tough. Not necessarily magical evil lord-god as the enemy.
I just don’t want to make it too grim. I don’t want DnD Midnight where all is essentially lost. I also don’t want counting every slice of bread because this is not the harshness I’d like to impose.
What worlds and work are you thinking of with the kind of general tone and scope you want to achieve?
my main thing at the moment is the untold stories behind Silmarillion - the humans of the East who neither had help from benevolent Valar nor had to endure the powers of Morgoth. The places forgotten by good powers but still messed with by distant evil powers.
