Players can select one out of 8 characters as their main character, and
they'll get to meet all the other characters in the middle of the game.
(And more, of course). Players don't get level up, but they get
individual Power, HP, etc up after normal fights, randomly. (Kinda like
FF II - the Japanese version, that is.) The stories differ from
character to character. The player gets to know pieces of the story by
playing each character, but they form a big picture. Basically, there
are 3 bosses, two of which were beaten a long time ago by a hero. Maybe
a few heroes... They leave 12 pieces of jewelry, and two of them are
lost. As the last boss is being reincarnated, the world became messed
up. So the eight people, for different reasons, start on their journies.
