Our hero Adol Christine, compelled by an unknown urge, travels to the faraway
land of Estellia, a land being overrun by monsters. There he learns that his
coming was foretold by legend, and that he will end the menace to the land.
Which unsurprisingly he does. In the process he and his companions search for
the six books of Ys, which hold both the answers to the mystery and the key
to the problem, battling both little and boss monsters all the way.
