To a certain extent, for now at least, all serialists are niche writers. Some of us however are even more painfully niche, perhaps you write your stuff in a particular narrative style, or an unholy mashup of genres is your lot. Maybe you write short stories or flash fiction, perhaps your main character is completely inhuman maybe you just have really weird content.
For one reason or another you are writing something that, as far as you know, there isn't many examples of. The issue isn't usually that nobody has done what you are doing, but that there is proportionally far less reference points.
Whatever it is that you write, when you write in such niche directions, there is very particular challenges to doing the writing. This Thread is a callout to those of you who are writing niche or weird stuff. Share your difficulties how you overcame them, or perhaps you haven't overcome them, share them anyway and your fellow authors might even help.
It may even turn out that your problem was actually really simple and loads of people have dealt with it before. Don't worry, the shame you might feel from that should be outweighed by the relief at not being quite as restricted in your writing.
I shall start things off with a rather basic issue really, which I dealt with a basic solution. Really this is actually a terrible example but it is what I come up with as an example half an hour away from midnight. Remember kids, never post moments before going to bed.
In my stuff some of the beings can't be described with a simple elf or dwarf or a description of a human with a funny forehead, this leads to issues with introducing large numbers of characters in a short amount of time (a general issue authors have to deal with).
Like most things, I deal with it by cheating. I basically make some of the characters animals or animate objects.
Animals and animate objects are my version of slapping a rubber forehead on someone and calling them an alien...
I think I'm going to stare blankly out a window now.
