Hey here's some ambience music i made for the server a while back; each song would replace a record and it'd be connected to a command block playing as ambience / music.
Things like birds chirping, people screaming in the distance, hidden "help me" messages and the pressure of being underwater.

Credit for all the sound material goes to http://ambient-loops.ambient-mixer.com
They are constantly uploading source material to mix and produce ambience. I did make mix and make all these tracks for Lore, but I did not make any of the source material!
Here's an example of an awesome loop someone made on it:

Give it a try! =)

This "Project" isn't one build, it's just some year-old works that are sitting around gathering dust. I thought I'd update a little on site.
If I made any repeats on photos, I'm sorry. Except for the forest temple area, that was purposefully converted, I no longer use the older version of that build for the City, so I'm not too fussed about it. I thought it felt more like ruins than anything else, like something out of Legend Of Zelda's forest temple.

That's the thing about builds people don't seem to often grasp. It's totally fine if you reuse builds for different purposes.
Why remake everything? Does your pride mean that much?
Just make cool things and have fun - that was the Sunfury way, and it was the time I most enjoyed minecraft.
It's your build. Do what you want with it! Copy that shit around 100 times and make it into something completely absurd, don't bother with getting serious on it.

Edit: The celtic link took people to dropbox, fixed it so it went to its properly listed url. Sorry about that.
