Very Unique Castle

This map is a unique one as it stretches above the sky to the center of the earth.

It also includes:
- a hidden railway that you can use if you ever need to escape
- a wolf farm
- a zombie farm
- a house within a fort within a castle within a skyscraper/base*
- lots of diamond veins
- lots of underground passages to explore. Just follow the stairs down the center of the building to enter them.
- built partially into a bay, partially on land

* This was my very first map and began as just an underground house. As I dug deeper, I also expanded outwards. This map is literally a house under a fort enclosed in a castle which is encased inside a skyscraper/base.

P.S. I built the wall around the castle using the toomanyitems mod. This may be useful to you.

P.S.S. If anyone runs a server, could you email me at lurpakjiminez96@gmail.com ? I think this could be a very good multiplayer map. Also, is there any tips for running a server on a Macbook Pro 13 inch?

Enjoy!
