The increasing demand for accessible and immersive digital experi-ences in Cultural Heritage (CH) highlights limitations in current Ex-tended Reality (XR) authoring workflows, which remain technically demanding for non-specialists. This paper presents a storytelling-driven XR authoring workflow implemented through HERIX, a modu-lar platform designed to support the creation of experiences without requiring programming expertise. The proposed approach embeds nar-rative logic directly into the authoring process, enabling heritage pro-fessionals to structure domain knowledge into layered interactive nar-ratives from shared multimedia assets. The workflow is oriented to-ward the generation of liquid XR experiences, allowing multiple XR applications to be derived from a shared narrative structure and asset library. To validate the approach, two applications in different modali-ties, Virtual Reality (VR) and Augmented Reality (AR), were devel-oped using the same storytelling structure and reusable asset library. The case study illustrates how a storytelling-driven workflow can re-duce fragmentation between narrative design and technical implemen-tation, while supporting iterative refinement, cross-platform adapta-tion, and narrative coherence across XR experiences from a unified au-thoring process. By transferring authoring control toward domain pro-fessionals, the approach can lower the technical and economic barriers associated with XR production, supporting more sustainable and scal-able approaches to immersive heritage communication.
