I want to write a fictional story that is set in a fictional setting created by me. It's a fantasy story, but it does not have things like magic. It simply has multiple sapient races (Dwarves, Elves, Humans) set in a fictional continent. Is this shirk? I am not creating any new religions. I have a disclaimer that everything in the novel is completely false.
Lying: Telling false statements and leading others to believe they are true
Fiction: Expressing your imagination by telling imaginative stories.The readers/listeners know that this didn't happen and that it's fiction.
Lying involves deception,fiction does not.For fiction to involve lying,you have to state that that story happened and that it is real
I hope this is enough to clear your doubts about this matter
As a writer myself I have heard from another Muslim writer that they try best to not mention any form of fictional religion. You can write stories but just be wary of promoting bad things within them. Especially if it a fantasy genre story don't incorporate anything about Islam or Muslims within it.
