End City

End cities are structures that are naturally generated in the outer islands of the End. They are tall castle or tree-like structures constructed primarily of end stone bricks, as well as purpur blocks and their variants. End rods are the only source of light. End cities are currently the only place where shulkers naturally spawn.

Generation
End cities naturally generate in the outer islands of the End, which are accessible via the end gateway portal obtained by killing the ender dragon. They are fairly rare; one can travel for hundreds of blocks without encountering a city.

Structure
End cities may spawn as a single tower by itself, or as a sprawling complex of inter-connected towers and pathways branching from a main tower. Within certain rooms (often at the top of the towering structure) are treasure chests and sometimes ender chests. Decorative purpur stairs protrude from the sides of the towers. Banners wave along the outside of some towers.

The rooms include:


 * Rooms which are three stories tall, with each room becoming more wider than the one below it.
 * Rooms which have banners hanging from the side and have a shulker hanging from the ceiling.
 * Rooms that consist of chests with very valuable loot.
 * Rooms that have an ender chest and a normal chest.
 * Rooms that have nothing in them at all.

The towers include:


 * Towers that are hollow, consisting of purpur slabs.
 * Towers that are three times as large as the hollow ones, consisting of end rods and shulkers.

End ship


There is also a small chance for an "end ship" to be spawned outside of end cities. These floating structures are comprised of the same material as end cities. They are also marked with a purple beacon that gives the Speed status effect, but that is a leftover testing feature which will likely be removed.

The inside of the ships are rather small. The first room inside the ship contains only a brewing stand, with two potions of healing. A staircase leads below deck to the treasure room. In this room lies two treasure chests, guarded by a shulker, that often contain highly valuable loot. Also in this room is the origin of the beacon, along with some obsidian that lines the floor of the ship.

Trivia

 * Some end city rooms are structured similarly to traditional Asian pagodas.
 * The banners atop the towers have a purple and black pattern that resembles the 'missing texture' block.
