I've been toying with the idea of adding some fantasy elements to my dystopian trilogy. As of right now, it seems as if I could add certain things without altering the plot, and maybe that's because I'm still in the midst of planning. It would be fun to give certain abnormal abilities to the minority of my fictional society. This minority has been preyed upon for years and is on the brink of extinction. Think in terms of the Jewish population if Hitler had proceeded with his tyranny, unobstructed by outside forces. This is an analogy of course; the trilogy is not about the Jewish people and Hitler. Maybe they can summon demons or curse enemies by work of voodoo. The majority(think Hitler) slanders this behavior[out of fear and jealousy] and so outlaws all of these activities while hunting down people who take part in them. I have these choices, but I'm not entirely sure the story would benefit from them...or fall victim to "characters who can get out of any situation you put them in because you gave them so much power". How do YOU personally figure out if these additions are beneficial or not to the story?
