From the introduction: The DC universe is long and storied one, in more ways than one. It’s a universe filled with adventure around every corner, not least among them on Earth, an unassuming but cosmically significant planet out of the way of most space territories. Heroes and villains, from the bottom of the Dark Multiverse to the top of the Monitor Sphere, endlessly struggle for justice, for power, and for control over the fate of the very multiverse itself.
