I wasn’t terribly surprised when the spell led me to the lower streets. Some of the streets downtown have two or even three levels. One is up on the surface, with the others stacked below it. A lot of the buildings have upper and lower entrances and parking as well, doubling the amount of access to the buildings within those blocks.

There were also plenty of empty spaces, pseudo-alleyways, walkways, and crawl spaces. Here and there, abandoned chambers in the basements and subbasements of the buildings above sat in silent darkness, waiting to be remade into something new. The commuter tunnels could connect down there, and there were several entrances to the insane, deadly labyrinth beneath the city known as Undertown.

Chicago cops patrolled the lower streets on a regular basis. Things came slinking out of Undertown to prowl the darkness. Traffic would blaze through on the actual streets, which were occasionally only separated from the sidewalks by a stripe of faded paint.

All in all, it’s not the sort of place a sane person will casually wander through.

I found Molly standing in one of the narrow alleyways. Snow had fallen through a grate twenty feet overhead and covered the ground. She was dressed in the same rags I’d seen the night before, with her arms clenched around her stomach, shivering in the cold. There was a fresh, purpling bruise on her cheek. She was breathing heavily.

“Again,” said a cool, calm woman’s voice from farther down the alley, out of sight.

“I’m t-t-tired,” Molly said. “I haven’t e-eaten in a day and a half.”

“Poor darling. I’m sure Death will understand and agree to return another time.”

There was a sharp hissing sound, and Molly threw up her left hand, fingers spread. She spat out a word or two, and flickering sparkles of defensive energy spread from her fingertips into a flat plane.

Molly simply didn’t have a talent for defensive magic—but this was the best shield I’d ever seen the grasshopper pull off.

A hurtling white sphere hit the shield. It should have bounced off, but instead it zipped through the shield, its course barely bent. The sphere struck Molly in the left shoulder and exploded into diamond-glitter shards of ice. She let out a short, harsh grunt of pain and staggered.

“Focus,” said the calm woman’s voice. “Use the pain. Make the shield real with your will. Know that it will protect you. Again.”

Molly looked up with her teeth clenched. But instead of talking, she raised her left hand once more, and another ball of ice flew at her. This one hit the shield and went through—but its path was attenuated more significantly than the last. It flew past her, barely clipping one arm.

She gasped and sank to one knee, panting. Magic taxes the endurance of anyone who uses it—and if you use magic you aren’t particularly skilled with, you get worn down even faster.

I shivered to see Molly like that. I knew how she felt. When Justin began teaching me how to create protective shields, he threw baseballs at me at top speed. When I failed, I was hit with a fastball moving at more than eighty miles an hour. Justin said pain was an excellent motivator, and that the activity was good training.
