A shadow has fallen over the 30th century, one that has not appeared for a thousand years. From an unknown corner of space, servants of an entity only known as the Darkness have emerged to collect both people and objects of power. These include the greatest foes the Legion of Super-Heroes have ever faced, ones that have taken the combined might of the entire Legion to defeat. But, to the Darkness, they are merely appetizer to begin his conquest of the universe.
