A narrative designer is responsible for crafting the story, characters, and world-building elements of a video game, film, or other interactive media. Their primary focus is on creating a cohesive and engaging narrative experience for the player or viewer.

Here are some of the key functions that a narrative designer typically performs:

1. Story development: The narrative designer works with the development team to create the overarching story and narrative arc of the game or media project. This includes creating character backgrounds, developing the plot, and designing the setting.

2. Script writing: The narrative designer writes dialogue, in-game text, and other written content that conveys the story to the player or viewer.

3. Quest design: For video games, the narrative designer may be responsible for designing and creating quests, which are the various missions and objectives that the player must complete to progress through the game.

4. World-building: The narrative designer creates the setting and lore of the game or media project, including the history, culture, and geography of the world.

5. Collaboration with other departments: The narrative designer works closely with other departments, such as art and game design, to ensure that the story and narrative elements are integrated into the overall project.

Overall, the narrative designer plays a crucial role in creating a compelling and immersive narrative experience for the player or viewer, bringing the story and world to life.
