My name is Duncan Grimshaw, A hunter, I just had been married to my wife and we still didn't have any children. One day, While exploring the Dungeon with my Party, we found a strange thing that people will never expect to find in the Dungeon, a child, a small black child that somehow lives in the Dungeon.Seeing that, I can only wonder ... how can a child exist in the Dungeon? who's are his parents?
