" I searched the plateau. Where was the Sandseed army? The earth undulated as if the sand had liquefied. The waves on the ground grew. I clamped a hand over my mouth to stifle a cry of surprise. Row upon row of Sandseed warriors stood. Camouflaged to match the sand, they had been lying on the ground in front of us and I hadn’t noticed them. "
