Tips for fantasy writers

Decide what magic costs
Brandon Sanderson's "first law" of magic says an author's ability to solve conflict with magic depends on how well the reader understands it. Limits make magic interesting.
Start small
You don't need a continent. One village, one tavern or one castle wing is enough for a short story.
Name things consistently
Use the fantasy name generator's sound-shape dial to give each culture its own feel.

Questions writers ask

What are good fantasy story ideas?

The strongest fantasy ideas combine an ordinary human want (belonging, revenge, love) with a magical complication. "A blacksmith who forges memories is asked to forge one that never happened" is more alive than "a chosen one fights a dark lord".

How do I start a fantasy story?

Start with a character doing something specific in the world, not with history or a map. Readers learn the rules fastest by watching someone bump into them.

How long should a fantasy short story be?

Most fantasy magazines accept short stories from about 1,000 to 7,500 words. Shorter works if the magic system is simple enough to show in one scene.
