EarthMC Map Addon

Installed on the client alone, the addon reads EarthMC Towny data and draws it directly on the Xaero's minimap and world map. Town claims appear with their real shapes, and the border thickness and fill opacity can be set in the configuration. Capital markers for nations can be switched on or off, and nation join range circles show where a town could join a nation within the 1,500 block radius. Nation radius circles mark the 5,000 block reach of a nation, with a union outline showing how nearby towns extend it.

Map worlds are handled separately. A Terra Nostra Moon world can keep its own claims and outposts, and the world button follows the dimension default. A click on the pin fixes the view to one world instead of cycling through them, and browsing one world leaves the minimap showing claims and terrain of another. Switching worlds on the world map follows Xaero's own dimension match, so lunar terrain can be explored with the same claim overlays. The addon requires Xaero's World Map and Xaero's Minimap, both of which must be present on the client.

The addon is released under the Apache License 2.0, so the code is open source. It is published for Fabric only, with files for 1.21.11 and the 26.x line, and its latest file is 1.4.8-26.3 for 26.3.
