At the very moment that the Wizard's heart stopped beating, the world changed irrevocably.
A thousand small evils awoke from their stasis and began to piece back together their shattered forms. All sought to corrupt and destroy the hope that spurred humans to do good and kind things to others, but of special note were the great sins - the Seven Deadly Enemies. Of all the evil defeated and pushed back by the ceaseless effort of the Wizard, the Seven were among the worst. So powerful, and so corrupt were they, that Mamaragan could not scatter them to dust like the small evils that he had crushed so often. All he could do was trap them in stone and keep them close, where his power could force them to lie dormant.
But now he was gone, and there was nothing stopping their reawakening. It was a slow process, and time moved strangely on the Rock. Days, weeks, months. It all blurred into a slow emergence, like waking from a coma. Each of the seven felt their brothers and sisters around them, and knew that their time to return had come.
Miles and worlds away, Billy Batson, Champion of the gods, felt like he was drowning under the stress of it all. His normal life as a young man, his duty as Shazam, and the careful balancing act that kept the two from colliding violently required constant maintenance. He was more tired than anyone had a right to be. His (mostly) excellent grades were slipping. He was getting up early to get his work done, trying to keep the few friends he had, working at the job that he had tried so hard and been so lucky to get, and learning the overwhelming skills that came with being Shazam.
He felt like he was slowly getting used to it, though. Especially when he was able to fly above the clouds, completely alone, breathing in the clean air. He could feel the vigor that he knew innately to be the stamina of Atlas pumping through his veins and recharging his tired body. His mind felt sharper, too. Even when he was Billy, he could feel the whisper of Solomon's wisdom call its secrets from across the void. It was nothing compared to the power he held in his hands as Shazam, though; Shazam's power was lightning in his blood. It was the best that he had ever felt, better than anyone had ever felt! The thrill of doing what only a superhero could do would never get old.
He had stopped a bus collision just a few days after the hydra was destroyed.
There was no thought, no inkling of "What should I do?" Just action. In a heartbeat, he had shouted to call down the lightning that transformed him and leapt into action. He carried the unstable bus to safety, scaring its passengers and denting the undercarriage some, but there were a dozen people surrounding him and thanking him. He had seen people act like this, but not around normal people. Certainly not around teenage orphans. They weren't seeing him, they were seeing the bolt across his chest and his stature. They only saw the hero. That's when the reality of what he had committed to finally hit him. Fighting the hydra, meeting Superman, everything that had happened so far was nothing compared to the realization that these people didn't know him, or what he could do, and they trusted him. He was their hero, just by being present. He was their protector, their Champion.
He was Shazam.
