I'm in a good mood so I'll let you in on this new project. I'm building this for a server with the intention of selling it. I can build servers like all the others with conventional arenas and markets, but this is more fun :)


P.S. The four colorful towers next to the main tower are elevators made by PG-5, an epic redstone creator who made this height accessible to players on servers who don't fly :)

Update
I've decided to make a whole new city rather than adding a magic district to the modern design. This new city will hold the magic district linked to the spawn (modern) science and industry district by fast travel rail through the nether.

Added a bunch of pics, more pics of this projects development can be found here: http://imgur.com/a/yKsi7#0

This thing has gone huge, but I'm only giving myself two more weeks to finish it. Wish me luck :)
