Not everyone is built to go out and fight in a war or kill monsters. These people make up the backbone of cities and towns.
These are not the only jobs you could have. This is just a list of a few possible ones.
Chemist- They work well with Grenadiers and Healers. They create potions, and other useful things.
Bard- Your basic pub entertainer. Lively singers or instrument players.
Blacksmith- They create the weapons for the kingdom. You can be an apprentice or own your own smith.
Dancer- Entertainers in the court.
Machinist- Fix and repair all forms of machinery, from guns to air ships.
Shop Owners- Own your own business! Bakers, florists, seamstresses, general stores etc.
Keep in mind the time period and current technology when thinking of these jobs. You can also affiliate yourself. For example, you can be a blacksmith for just a clan branch or for the army.
Remember, these people are desperately needed in order for the kingdom to flourish!
