There are many helpful writing mnemonics, and several of them are referred to as the Five C’s. For example, the Five C’s of Communication are a list of five qualities to aim for in any oral or written communication: clear, cohesive, complete, concise, and concrete. I’ve seen several variations specifically focused on storytelling. For example, one source lists circumstances, curiosity, characters, conversations, and conflict. Indeed, all of those are vital elements of a story. Another source offers a different list of the Five C’s of Storytelling: characters, conflict, cure, change, and carry out the message. There are many others. In the story structure exercise above, you use the so-called Five Commandments of storytelling to craft a story, so you could consider those elements (inciting incident, progressive complications, crisis, climax, and resolution) the Five C’s. You don't have to pick one. Any framework like this can help you craft your story.
