Just....huge. Inspired by CNB's batcave, this is going to be a massive, secret under-ground building with many automated systems and traps. You can see it right now by connecting to this server: 108.170.48.50:25576, saying /warp admin, then right clicking the up-most redstone ore (To open the hidden entrance.) Go down the stairs and into the main chamber. Currently, the only finished rooms are the main intersection, and potion room. The main room includes a fake door, with 7 levers, labeled Enter, and 1-7. If they get the code wrong, they die. If the code is right, the room comes to life and the three 3x3 doors open. In the potion room, placing a redstone torch on the diamond block will cause buttons, potion stands, and water to be revealed. These buttons all dispense potion ingredients from above. You can see the main chamber on your own, but in order to see the potion room, I must be there, for the area is safe-zoned. Comment if you would like me to show you it in action! If this gets enough attention, I MIGHT upload it when finished. (More diamonds = better chance of world AND schematic files.)
