Final Fantasy: All the Bravest

"When the shine of the sun is hidden by the shadow of the moon, the worlds unbound are brought together, and the gate between dimensions thrown open. From the sun, under a pall of black, surges forth a sinister host, together with a darkness, eternal and unyielding, that threatens to consume all. To repel this vast evil, Warriors from all over worlds must unite. Tho fight to come is theirs, and it is a war whose end cannot be seen. These fated heroes have risen, each with a Crystal brilliant to behold. They stand now not alone, but united, and in numbers greater than ever imagined."
