If the march of the soldiers happened where players could see, they would naturally be curious about what the event was going to be. Not only that, but it looks badass enough that many will try to capture a video on this, post it on media platforms, and brag it to their viewers or even friends. Thankfully, we are far from the eyes of players right now especially since this was an area that is unexplored by players, and by default, we are the first ones to experience the harshness of this place.
With the help of one of the magicians, they created a tunnel that will allow us to descend down the underground directly by terraforming the ground and creating stairs that would act as a path for us to enter and exit. I volunteered to write the map to avoid getting lost once we are starting to move around. I know how important it is during my time when I was underground. I know it wouldn't be useful for now, but it will once it is filled with paths. Getting lost would be disastrous.
