This is diagnostic tooling for fiction writers whose settings feel thin or unconvincing. It walks you through seven world states, from backdrop worlds to flat non-human species, and points you toward specific interventions for each. The consequence cascade framework is the core piece: trace any speculative element through direct effects, systemic adaptations, and cultural evolution. It's opinionated about common failures like monocultures and convenient technology. Think of it as a checklist for whether your magic system has actually transformed society or your institutions feel like they evolved rather than got designed last Tuesday. Pairs with other worldbuilding skills for the actual construction work.
