A palace hall naturally couldn't block the road; in actuality, the Star Brilliance Palace Hall was situated inside a gorge. This gorge was the path that had to be taken from the Nine Nations of the Desolate North to the north region.
This gorge was called the Fallen Moon Gorge. According to legends, this was originally a tall mountain, and the north region ended here. There was no way of crossing it because on top of the mountain a terrifying presence circulated, and even Spiritual Infant Tier cultivators would fall victim to it.
However, an unknown number of years ago, the night sky's moon suddenly fell, chopping the mountaintop into a gorge, and thus it received the name of the Fallen Moon Gorge.
