Nielas Aran's actions were very strange. After sitting on the floor for a while, he stood up and began to walk around the room. After walking for a while, he sat down and began to mumble to himself. Basically, he kept repeating these actions over and over. Anyone could tell that something was wrong with him.
In fact, this was the case. Nielas couldn't leave this room at all. Although his soul resided in the present world in the form of a ghost, he was bound to this room. After any intelligent life died, if their soul couldn't go to its destination and remained in the world, it would inevitably slowly dissipate. This room allowed Nielas's soul to continue existing, but it also turned him into an existence like an earthbound spirit.
He was trapped in this room day after day, year after year. In his ghost state, he couldn't eat, sleep, or even touch most objects in the world. This boring life was actually torture. Any longer, and even his soul would go crazy.
