So, you may be a bit confused. I began development of Midnight Mountains a year ago, but it took a little over 4 months to complete enough to be shared. The Midnight Mountains are an alternate dimension that is an endless expanse of bluerock. You can enter it via doors that appear randomly, seemingly without purpose other than being a door in the middle of nowhere. Sundown Valley has some references to Midnight Mountains, but Sundown Valley isn't canon.
