Recently in the Terrai region, the two most sacred legendaries have started a full on war with each other, the war of Day and Night. Because of their rage, their powers grew stronger, this made the villanoous Team Darkrest want to capture the legendaries even more than before. An unknown person had sent a note to a trainer (the player) telling him/her that they must capture one of the legendaries before there powers grow stronger and Team Darkrest uses them for an evil purpose. The trainer must grow stronger and battle Team Darkrest on their journey. The will become worthy to tame the mighty legendaries of Terrai.
