Creativity is Intelligence having Fun Hard science fiction demands internal consistency. Your FTL system needs rules. Your alien biology needs logic. Your political structures need to follow from your physical constraints. One careless detail can break reader immersion. Forge Constellation gives hard sci-fi authors a structured world-building pipeline. Upload your technical notes, research papers, and reference documents into Aether Forge. The RAG engine lets you query your own research library: "What propulsion constraints did I establish for interstellar travel?": and get answers grounded in your actual source material.
