A surprising number of worldbuilders don't know that what they're doing is called worldbuilding! Ever designed a new race for a story? Ever described your character's home? Ever invented a magic power for your character? Ever recounted a fictional historical event? Of course you have, you big fat worldbuilder, you! If I gotta be succinct, I describe worldbuilding as "any act of creation to do with the setting, lore, or rules of the world your story takes place in, whether that's how a Fireball spell works, or the exam schedule of a fictional high school." How do you guys explain it?
