Could you build this?
Partial While the lore notebook, character sheets, and AI wrappers are standard CRUD, building a robust, real-time multiplayer Virtual Tabletop (VTT) with synchronized state and dynamic fog-of-war is non-trivial.
What it would actually take: The system requires a web frontend (Canvas/WebGL or PixiJS) coupled with a real-time multiplayer backend using WebSockets or WebRTC (e.g., LiveKit or PartyKit) for authoritative map state synchronization, dynamic lighting, and token movement. Generative AI APIs (text and diffusion models) handle content generation. The hard part is managing high-performance multi-user canvas rendering, collision, and low-latency state synchronization alongside full 5e ruleset integration.
