Journeyed there and back again
Sort of off topic, but does it stand out to anyone else as odd that horses, rabbits, and wolves seem at home in worlds that include all sorts of fantasy creatures? I suppose its just easier than inventing something more interesting to do the same job.
Obviously you need to create some unique elements to make your world memorable. But I believe Sullivan was saying save that stuff for things that are cool and not the name of the temperature gauge or a new name for a horse like animal. I agree with that.
