Feature request: Custom Explorer Maps (https://minecraft.fandom.com/wiki/Explorer_Map)
It is possible to use datapacks to create explorer maps that target different structures than just hidden treasure (for example, ancient cities or Strongholds). See example of such datapack here https://www.planetminecraft.com/data-pack/ancient-city-explorer-maps/
Denizen, however, unfortunately lacks the functionality as far as I am aware. It would be great to be able to create custom explorer maps pointing to structures or any location you wish to define!
Minecraft Wiki
An explorer map is a special map used to aid in finding rare generated structures, including woodland mansions, ocean monuments, and buried treasures.
