Woodland Mansion

"What are the Illagers doing in that dank, secluded mansion of theirs? With its redstone jails, elaborate altars and hidden rooms housing strange obsidian structures - it really seems like they are plotting something."

- Marsh Davies

A woodland mansion is a very rare structure found only in dark forest biomes. It is the only place where the vindicator and evoker mobs naturally spawn.

Generation
Woodland mansions generate very rarely in dark forest biomes, often appearing tens of thousands of blocks away from the spawn. They can be located with woodland explorer maps, which can be bought from cartographer villagers with emeralds, or the command.

If the player is playing with the Customized world type, woodland mansions will not generate in dark forest biomes if the biome size is changed or if the ground is too low (higher ground will work fine).

Structure
Because it is generated randomly, the exact structure of a mansion varies. All woodland mansions have these in common: they typically have 2–3 floors, with a wide variety of different rooms, and generate a cobblestone foundation underneath the entire structure (much as a village house does). The top floor is always a bit smaller than the main floor or floors below. A large foyer and a winding maze of corridors are also present in all mansions.

Rooms
There are many different types of rooms in a woodland mansion. Not all rooms are readily accessible - some have sealed entrances, others have no entrances at all. A particular woodland mansion might not contain every type of room, as the interior is randomly generated.

One may access the individual structures of a woodland mansion by utilizing structure blocks to manually load room structures from the  folder in minecraft.jar. To do so, set a structure block to Load mode, enter, and press LOAD. A list of possible rooms, the names of these structures, and small descriptions are provided in the table below.
