Unknowingly in tandem with Markus, she glanced over at the car battery as it began to draw power, quietly holding her breath. A moment later, the air around the table seemed to grow numb or muted, as if sound wasn't traveling through it at the same rate as the rest of the room. Or perhaps, energy in general. That was a good sign--at least, as long as it didn't explode beyond the boundaries of the spell. Who knew what an untethered nullification might do to them.
She heard Markus' breath and glanced over at him, before looking back to see the light die from the rune circle. She exhaled as well, and then, a few seconds later, let her shoulders unwind. “Not bad,” she murmured, cautious with her praise. She would wait until Markus handled the item to see if it was as stable as it looked.
