The Selkirk Mountain Base

Hidden deep within the Selkir Mountains is the mysterious home of Rubix One. Hidden inside Mount Selkirk, this house is filled to the rim with redstone contraptions and hidden secrets. Lined with redstone wiring and secret passageways, the base is as much of a redstone contraption as it is a network of hidden hallways. It is by far the biggest redstone creation Rubix has ever made. In fact, he has been working on it over the course of several months. Now, it is finished.

*There may be a few things that I missed, as the base is so massive making sure every single build inside is listed here can be difficult sometimes. I have tried my best to make sure every single creation is listed.
