Here is a
How to Write Fantasy Novel
1. Writing fantasy-genre sentences takes a lot more work than writing normal sentences.
"If thou h'ain't put in the work, then don't deign to twerk!"
-Duchess Miley of the Mulletted Four Bears
2. A character can be named many, many times, and any confusion is the reader's fault. Trolls will know a character by one name, dwarves by a different name. Remember nobody is all things to all men. So King Kalsius may be known to the pixies as Clumsy Clodhopper The Man with the Heavy Feet, because of his heavy, metal armor boots.
"Hello, Clumsy Clodhopper!" squeaked Mr Babbles.
"Shuddup already! I'm a king and I'm trying to impress my mistress here!"
3. Make sure that you have guilds, masters and apprentices, and characters that have occupations in keeping with these guilds and apprenticeships. Master builders need their masonry apprentices, and their sculpture apprentices, and these apprentices require backgrounds that make for good dramatic irony!
When your apprentice was a child, he killed a goose so that his destitute family would not go hungry. But he believed the goose was a swan. He went on the run, fearful that the swan was royal property. There is dramatic irony in the reader knowing that he killed a goose rather than a swan, and that he has lived a life on the run for no good reason. But how he came to become an expert stone whittler?
That's up to you!
4. In fantasy writing, you can never have too many seamstresses in a scene. If you are confused about writing a scene in the fantasy genre, ask yourself one question: "Could this scene do with another seamstress?" The answer is invariably Yes. Turn as many of your monsters into seamstresses as possible. Nothing says more in terms of depth of character, than a double-jobbing monster, living in her cave, as a seamstress.
5. Make your emotions real, but make sure the story moves forward if you supply a map, with a lot of sprinting over land.
Some of the most emotionally-riveting scenes in Lord of the Rings involve Shelob the dirty big spider, Orcs, Samwise and Frodo. But there's a map, and those little hobbits are stuck at one spot on that map for all of that emotional trauma! This is very frustrating for those fan-boys who love their cartography but don't appreciate good writing!
If you supply a map, make sure your heroes and all of your characters are running at full tilt, all of the time, whether being general-anesthetized by spiders, captured by orcs, visiting a tavern for a dram of mead, or undergoing other emotionally-exciting or conversational stuff. The orcs can carry your heroes for extended periods on a litter or a stretcher, sprinting along.
And don't forget any inn-keeper's tavern will be more than capable of flight if he's got any magical skill at all. Remember too that calling an innkeeper "crafty" says more about the range of beers he stocks than about his personality.
