How does an idea evolve into a fully formed narrative universe? What challenges arise when writing science fiction audio dramas? How can science and quantum physics become creative engines? In this masterclass, screenwriter and sound creator Julio Rojas, author of the award-winning audio series Caso 63 (Rose d’Or Award for Best Podcast 2024 and Ondas Award 2022), will share his creative process — from the seed of an idea to developing a story map, a series bible, or a pilot episode. He will also offer his personal insights on the evolution of the genre and the future of audio fiction, both creatively and commercially.
