Setne gravity

I dropped to the ground at the archway as a massive roar shook the courtyard. Trees were uprooted.
Windows shattered. Bricks peeled off the wall, and everything in sight hurtled toward Setne as if he’d become the new center of gravity. Even Annabeth’s magical bonds were stripped away. It took all my strength to hold her with one arm while gripping the corner of the building with my other hand.
Clouds of debris spun around the magician. Wood, stone, and glass vaporized as they were absorbed into Setne’s body.
Once gravity returned to normal, I realized I’d left something important behind.
