When the game starts, you learn that you are the group which is being sent to the surface to investigate. It's been many years, and no one knows what will be up there. You start with a party of four characters. Each can either be a Human, a Nephil, or a Slith. Humans are average, Nephils are good with ranged weapons, and Slith are good with polearms. However, the Nephil and Slith suffer a 10 and 20 percent experience reduction, respectively. After you choose the races, you can choose the classes. These ten classes range from your basic warrior to the rebel, who is proficient in many things, to the shaman, a magic user who commands magic while being able to fight. Adding to this, you may create your own custom class, changing stats and adding feats and skills.
