Auroradle Sphere

From my crystalline arch, I see the magic spheres ignite. Each carries a different spell—ember, frost, lightning. The wand at the bottom slides left and right, deflecting them back into the air. Every successful catch feeds the caster’s score, but the orbs grow quicker, hungrier. Soon, a second sphere joins the dance, then a third. One that slips past the wand will shatter against my stones, and the game dies. How many will he hold aloft before the storm consumes him? I keep no count, only watch.
