Shows villages, temples, fortresses, and 16 other structure types as markers on your BlueMap web map. Each structure type gets its own toggleable layer in the sidebar with a custom icon, and markers include a /tp command you can copy. Positions are computed directly from the world seed -- same algorithm Minecraft uses -- so it doesn't need to load any chunks.
Fabric server-side mod for Minecraft 1.21.11.
- Per-structure toggleable marker sets in the BlueMap sidebar
- Zoom-based visibility (dense structures like shipwrecks only show when zoomed in)
- Copyable
/tpcommand in marker popups - Configurable search radius and per-structure enable/disable
Requires Fabric, Fabric API, and BlueMap 5.0+.

Structure positions are calculated from the world seed using the same grid-based algorithm as Minecraft. Each candidate position is validated against the server's biome data via BiomeSource -- no chunk loading required. Valid positions become POI markers on the appropriate BlueMap dimension map.
