Two very different sorts of travelling could feature in your story.
The characters will probably need to get to other places at some point – places that are too far to reach on foot. The time and place will determine the mode of transport they use. Obviously they won’t travel by car or bus or train in the sixteenth century. But it’s not enough to plonk your characters in a carriage. You have to know what the carriage looks like, inside and out. You have to know what it feels like to ride on the roads of the time, and how often they stop to give the horses a rest or to leave the horses behind and continue with refreshed horses.
They might ride on horseback. In another part of the world, they might ride on camels or elephants. Have you ridden on those animals? I have. When the camel gets up, it feels as if you’re at a fun fair and about to be turned upside down.
Then there’s the other sort of journey that traverses time. For some reason I haven’t managed to find the answer to this question: in a time-travel novel, who or what does the travelling? Is there one character (or more) who starts off in one year and find herself in another? Or does the story do the travelling by showing two or more different eras in which the characters are connected in some way? Could someone explain, please?
