Medical Valley
The Medicine Valley is considered one of the most important places in the whole Order. It's because of its existence that the Order can conduct its affairs in maintaining some semblance of peace and structure around the continent, despite the severe manpower shortage and a large area to supervise.
Other than training, and using every resource they have to ensure the growth of all who step through their doors, the existence of the Medicine Valley was another key component towards the growth of the Order.
The cultivation world being as dangerous as it was, even with high talent coming through its doors, the Order would not have survived as long as it has, without the presence of the Medicine Valley, especially during the early years when the Order was just making its presence known.
Wars were still constant, and the Order was spread thinner than it was now, it had less manpower then, and its name did not have as much deterrent as it did now.
