I've recently run into a dilemma while working on one of my stories and I wanted to gather the opinions of some other people. Is it too out-of-place to use modern everyday curse words in a fantasy/sci-fi story. In my case, the world I created evolved from our own, but I'm still not sure whether or not modern swears would work. I was thinking of creating my own, but am hesitant to do that because they might not have the same impact. I was just wondering what other people thought about this.
