I was inspired by Euclides (his Ultimate Underground Redstone Bunker [w/ 150 redstone mechanisms!]) to make a base. This base is in the side of a mountain. THIS BUILD IS NOT AS GOOD AS Euclides!!!
This world may have things to be changed, but it was to be a small project to start with.
IF YOU WANT ME TO ADD SOMETHING, JUST ASK FOR IT :D

PS: You may see me using x-ray coordinates in the photos. I assure you that is so I may see where other rooms are so I can easily make rooms big enough without going into other rooms (or seeing redstone).
