Subplots are the unsung heroes of the story world. They're like the supporting actors in a play, providing depth and interest to the main plot without getting too many lines.
Or in other words, they're the reason your favorite TV show is still on episode 12 of season 3.
Character Subplots are where the real drama is. Who's gonna get together, who's gonna get it out, and who's just gonna get lost in the woods.
Setting Subplots are all about the world building, baby. From the dusty old tavern to the haunted mansion with a twist.
