End dimension update ideas

Biome:

• Regular one can have an amplified terrain
• A new biome can have "End Wood" which has a chance to randomly teleport after breaking it
• A sub biome can spawn endermites naturally but not enderman

Structures: 

• Void City (Hangs in the void between islands hung together by a block of your choosing
• Endshaft (Same as a mineshaft but in the end, maybe you can find ores in there but instead of stone or deepslate, it's end stone versions)

Mobs:

• Telecat (a cat that when falling teleports to the ground instead of not taking damage like a normal cat. allows you to set your spawn in the end but can't sleep there)
