Not sure what you dont like about my post. I tried to showcase in simple ways what I mean. But I am happy more people agree with my fear to make the game boring and generic.
An even better example is a scene in Lost Ark. Characters that we have been getting close to. Women and children we come to like, are slaughetered by the church for just being in a demon infested area and suspected of being tainted. When a priest and close friend of us find out about it his inner demon(he is part demon) get released and he kills his former comrades. Then join the demon to destroy the church.
Another good example is the scarlet crusade in wow. They are so hellbent on destroying the undead that they torture and kill inocent people they suspect. No proof, no rational thought. Religious celots that see nothing but evil around them.
About the bearan. When I heard shortly about them I just had one hope in mind.
The bearan is not friends with humans. They tolorate them and try to hinder them from invading and destroying nature and upset the nature spirits. This ofcrouse make them despise dwarfs that could be looking for scientific progress and industry. They are in a way keepers of balanse between human settling and the wild. So unlike Elves they dont just like nature, they are ready to irradicate humans if they overstep and risk destroying nature. This could make for some intresting story development.
Keep in mind that in the old days, when witch hunts happened, many innocent women were drowned, burned alive, etc.
The church didn't need much to say that a woman is a witch and therefore kill her.
Also think about the Crusades of the Church, again same stuff, fanatic religious army killing in the name of the church.
These are real historical examples, not just fantasy written lore. I don't see anything bad in that unless the whole game is based on that, not a problem to have a group of religious fanatics, or devil worshipers, or different groups. It is part of history :)
