beneath the DC multiverse we've grown to know lies a dark secret. For
every Earth, there is a negative counterpart. For instance, Earth 0 has
Earth -52, Earth 22 has Earth -22 and so on. However, it wasn't always
this multiverse was known as the "World Forge". Rich in dark matter and
precious metals, it's one resident - a cosmic entity known as the World
Forger - could create countless universes. If a universe was a sucess,
it would rise to join the Orrery of Worlds, while worlds that failed
were destroyed. That is, until Barbatos - the Great Dragon and destroy of universes - revolted and took the realm for himself.
Instead of destroying failed worlds, Barbatos
allowed these worlds to exist, thriving on the destruction and
suffering of all sentient life that lived on them. From these worlds
came seven of the darkest knights ever seen. However, when he discovered
the Batman Who Laughs, the Great Dragon set his sights on the "true"
multiverse above them.
