Underground quartz mansion

Hey guys, it's superslash9 here and I have felt the sudden urge to build a massive underground structure. So here's the deal: Right now I have only gotten the first few rooms in so I don't have pics or downloads. When I get to 50% however, I will upload both of the two. This structure contains many features including decorations, secret rooms, minerails, many other fun features, and it is a perfect structure if you want to do a survival but want a head start. I will add more about this later, as I make more progress.
