A large hole lies in the center of the large city Acttio. The hole spreads diease and sucks life from the country. From appearances the hole seems to be man-made due to it being covered in strange mechanical devices and abandoned buildings, nobody knows what lies at the bottom. Few try to descend it but the few who try never make it back. However one man, no… One boy plans to reach the bottom, not for a lofty goal or purpose, the only motivation he has is an unbearable curiosity.
