Honestly, one of the things I love about classic sci-fi and fantasy, especially foundational stuff like the Conan stories, is how little of a shit these authors gave for what would one day be the “rules” that define the genres.
For instance, in a sword and sorcery series I do not usually expect to encounter an immortal flying elephant man from outer space.
I am not joking. This is a thing that is in one of the stories. This is, in fact, the thing that one of the stories is about, the revelation that its all leading to.
God, I love these stories.
