The entire quest is built completely underground. there are twenty steps in all to get to the treasure room, which is a storage room with chests filled with goodies. There are traps which you must beat, choices you have to make and mobs you have to kill. At first, it's easy, but gradually gets harder as you move on until you finally reach the final step, which is rather very simple. All are redstone powered and fully functional. Throughout the entire journey, you must make quick decisions and think 'outside the box' if you wish to make it to the end. I challenge you to take the impossible journey to the treasure room. Of course, it'll be much more fun if you do it in survival mode in anything but peaceful difficulty and with no mods that will help you out. I won't stop you, but for you to get the most fun out of it, I suggest you go without aid.
