Post History

A wise writer chooses a point of view that enables the reader to see what they need to see of the story. If you choose a point of view arbitrarily, or because it is fashionable, you will often find yourself stuck with no natural way to show the reader what they need to see. You will then be stuck trying to engineer some method to *tell* the reader what they cannot see by some weird manipulation of dialogue of plot. And when you do this, it will seem odd, and it will take the reader out of the story. 

So, the best and most natural way to tackle this problem is to adopt a point of view then does enable the reader to see what they need to see. If you are dealing with a world that is entirely alien, where the reader can bring no assumptions of images with them to the story, they are going to need a guide, a storyteller, who can show them the world of the story. 

This can be a third person omniscient narrator (the simplest choice) or it can be a reflective first person narrator (as opposed to a stream-of-consciousness first person). Either way, though, the narrator has to acknowledge that they are describing a world different from the reader's own, and therefore speaking to a reader from a world different from their own. If you are not willing to do that for a character in your story, then you are left with the external narrator. 

And note that that is the narrative voice of the vast majority of fantasy stories traditionally -- and for just this reason.
