In my Fairy Kingdom, any use of magic drains energy from the user and all fairies have to top up regularly from the Queen’s Fountain of Youth (the witches make their own arrangements!). So devices or machines that can be used to carry out a task often are used so magic is saved for when there is no alternative.
For instance, broomsticks are used for travel. Where the witches do use magic is to make the things more comfortable to ride! Wizards use magic to speed up the devices they use (and not just for travel). So the idea of travelling light in my fictional setting is to limit the use of magic and therefore limit the amount of energy used up.
How do your characters travel light? If there are travel restrictions dependent on what class you come from, how do they get around these or exploit them if they are one of the “entitled”? Also what dangers do your travellers face? Can they use light as a weapon to defend themselves with if necessary (and yes I am thinking of the light sabre here!).
