Woodland Mansion

"What are the Illagers doing in that dark, 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

Woodland mansions are large, rare structures found only in Dark Forest and Dark Forest Hills biomes. They are one of the only places where Pillagers spawn naturally (the others being patrols, raids, and pillager outposts) or where a totem of undying can be obtained (from evokers, who drop them, also spawn in raids).

Generation
Woodland mansions generate very rarely in Dark Forests and their Hills variants, often appearing tens of thousands of blocks away from the spawn. They can be located with woodland explorer maps, which are obtained by trading with cartographer villagers, or with cheats enabled using the command.

Like most randomly generated structures, woodland mansions can be found more frequently in a world using the Large Biomes world type.

Structure
Because woodland mansions are generated randomly, their exact structure varies. However, all woodland mansions have several things in common: they all have 2–3 floors, with a wide variety of different rooms, and generate a cobblestone foundation underneath the entire structure; the top floor is less than half the size of the lower floors, and they all contain a large foyer that leads to a winding maze of corridors.

Rooms
Any given woodland mansion will contain many types of rooms, and since the layout is randomly generated, some room types may not be present. Furthermore, certain rooms within the mansion may not be readily accessible - some may have sealed entrances, and others may have no entrances at all.

One may access the individual structures of a woodland mansion by using 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.
