If you have Conquest Reforged, the mod uses World Edit to load and save schematic files. Within your Conquest Reforged folder, you should look for (or search for) a folder called "schematics". I don't specifically remember the path, but you should put the .schem file in there and make sure you know the name, or rename it to something you can remember.

In game, you use the command //schem load filename

Replace filename with whatever you've called the schematic.

I've just uploaded the schematic.
There have been some changes because I modified the map to be functional without Chisels and Bits. It only needs Conquest Reforged.

I'm happy you think it's so similar! I studied many pictures very closely to be as accurate as I could :)
