Shazam!

As I was walking to Karyn’s house from the park, I decided to take a shortcut through an alleyway, when suddenly as I was turning the corner, I was struck by lightning and transported to a dark cavern! In the cavern there were only three things: an giant orb that glowed many mystical colors, a doorway to what appeared to be larger rooms, and in the middle of both, a stone throne, with an elderly woman wielding a mighty cane sitting in it. In fact, it had been the same old woman I rescued!
“What’s going on here? Wha-“ I asked, knowing full well this resembled the origin of Shazam, the original Captain Marvel. What confused me was the old woman right there.
“Hello Jon. My name is Shazam!” The old woman replied, “I am an old sorceress from centuries ago! I had once protected this earth, but as the years went on my power waned and waned, until all I could do was subtly alter minor things. I saw your bravery today, you stood right up to an armed man and held him down to rescue a little old woman, actually me in disguise. Few would have done that.” There seemed to be joy in her eyes, like she truly found someone special. “I have decided to make you my champion of justice! Captain Marvel, the Miracle Woman!”
“Wow, this is amaz- Miracle Woman?” I asked, just getting hit with had Shazam had just said. That was...unexpected.
“Yes, all my champions are woman! They have to be, as they are channeled by the power of the mainly female goddesses. I also prefer it, and I’m keeping it that way. Now, will you accept this amazing gift?”
