Iron Farm

The Iron Farm is just west of City Hall, past Student Housing. It's hard to miss - its second level rises almost 100 blocks in the air, separating two synthetic villages.

Golems from the villages drop into a lava blade, and iron and poppies accumulate in a chest. The village chunks are not loaded unless someone is in the area; working in the garden outside City Hall is close enough, but inside the building itself isn't. The farm should produce about a stack of ingots per hour the chunks are loaded. The poppies are planted in the enclosure at the base. Gracious players put at least some of the iron collected in the minerals chest in City Hall.

The upper farm has not yet been confirmed to drop a golem; its spawn floors aren't sloped like the lower village and all its villagers are in a single pocket, but otherwise the two farms are virtually identical. It may need some debugging, however.

Location
The Iron Farm is on the western outskirts of Pickaxe City, and the enclosure pre-dates the block layout. It slightly overlaps the Mushroom Farm block.
