I forced myself to focus, and I spoke the most powerful of all divine words: “Ma’at.”
The hieroglyph burned in front of me—small and bright like a miniature sun:
 “Good!” Walt said. “Keep at it!” Somehow he’d managed to pull in the chains and grab the sphinx’s snout. While the creature bore down on him with all its force, Walt’s strange gray aura was spreading across the monster’s body like an infection. The criosphinx hissed and writhed. I caught a whiff of decay like the air from a tomb—so strong that I almost lost my concentration.
“Sadie,” Walt urged, “maintain the spell!”
I focused on the hieroglyph. I channeled all my energy into that symbol for order and creation. The word shone brighter. The coils of the serpent burned away like fog in sunlight. The two criosphinxes crumbled to dust. The canopic jars fell and shattered. The Anubis statue dropped Khufu on his head. The army of shabti froze around Alyssa, and her earth magic spread through the room, sealing cracks and shoring up walls.
I felt Apophis retreating deeper into the Duat, hissing in anger. Then I promptly collapsed.
