A FoundryVTT module that lets one table see, live, what other tables are doing across the same fantasy world. Foreign players render as lightweight canvas sprites — no tokens are spawned, no database is written to, no permissions need wrangling. The first concrete piece of the long shared-world vision.

It connects to a geomqtt broker over MQTT, subscribes to the tiles your viewport is showing, and draws whatever moves through them. Compatible with Foundry v11–v13.

A small daemon that bridges Redis’s geospatial commands and an embedded MQTT broker. Drop tile-keyed coordinates into a Redis GEO set; any client subscribed to the matching tile topic gets the update on the next tick.

It is the transport layer that makes the rest of the shared-world experiments possible — Foundry tables, web clients, and Unity/Unreal sessions can all listen on the same tiles and see each other move.
