Worldbuilding takes a lot of imagination and creativity but there are some very simple rules to follow when creating a new world for your fantasy creatures to live in.
1. Make your world realistic- When you are creating your fantasy world, it has to be at least a little realistic. If it is a space age adventure, then hoverboards are fine. If you are creating a story about dragons in Medieval Britain, hoverboards may not be the way to go.
3. Actions have consequences- This is especially important if you are using magic in your novel. When your antagonist uses his/her magic, there will be a response to this whether it be natural or man made. Magic impacts on the laws of nature and disrupts the cosmic peace. Bear this in mind and use it to your advantage and you will enjoy writing it even more.
4. Beware Deus Ex Machina- There are no free passes in fantasy. Your hero cannot suddenly wake up to find that it was all a dream. You must have a logical explanation for everything that happens even if it is only logical in your fantasy world.
5. Every Rule has it's exception- By all means you can be the exception and break all of the rules of worldbuilding but if you do so, know which rule you are breaking and why you are breaking it. Give your reader valid justification for breaking the rules.
Worldbuilding is one of the most fun things to do when writing but you must ensure that it is done correctly. Hope this has been of help to you writers out there.
