Organization headquaters

Within a small mountain range there stands an ancient door, reaching upwards by about ten or so foot. Intricate carvings and words of a lost language, the doors are far too heavy for any normal being to open alone, along with that the door is well hidden. Behind the doors you will find the head quarters of the Organization, never has anyone not with the organization entered the realm and survived. So you have been warned…Though if you are with the Organization you will find all you need, it is simply a city hidden away.
