Yesterday's Bread – a modern MUD with AI NPCs and a personalised novel

Hi HN — I'm Bridgette, a software engineer in South Africa. Over the last year I rebuilt a classic-style MUD from the ground up on a modern stack (Postgres, server-authoritative simulation, generative-AI NPCs that keep schedules and remember conversations, dynamic weather, item decay, the works). The twist is that when you finish the single-player arc, the game compiles your run into a personalised PDF novel — your name, your race, your choices, your ending. I'd love technical feedback on any of it: the simulation, the NPC design, the localisation engine (it's bilingual English/Afrikaans), or just the idea of "the game writes you a book about you" as a finishing reward. Happy to answer questions.
