DC: Dark Legion

Earth has never faced a crisis its heroes couldn’t solve. Until now…
 
When a massive tower rises out of nowhere in the heart of Metropolis, the rest of the world reacts as if it’s another one of the crisis events they’ve seen before. People are concerned, but confident Superman and the Justice League will keep them safe. And that’s how they feel until Superman, Batman, Wonder Woman and several other heroes enter the area around the Tower…and don’t come back.
 
It seems the dark times have barely just begun...
