The outcome of Macbeth's conflict with Banquo and Fleance is that Macbeth tries to have them both murdered, but Fleance escapes. In Act III, Scene iv, as the murderers are trying to complete their task, one says "There's but one down, the son is fled". This shows that Banquo has been successfully killed but Fleance has escaped.
Fantasy can be any sort of thing, it can be a dystopia, a utopia, it can even just ignore those. I dystopia is a type of fantasy where the world the character lives in is worse than the one we live in now.
