I drew in a breath and threw another blast of Stone magic at the ceiling, even as I reached for my Ice power, making the frozen droplets and stream of water expand in size. I forced the Ice into the stone like a chisel. Ice, stone.

Chisel, hammer.

My vision became a field of silver. Sweat dripped into my eyes, my knees trembled, and my whole body felt weak. It felt like I’d been toiling away for years, decades, even though only a second, two tops, had passed. I wanted to let go of my magic, wanted to rest. Every part of my aching body screamed at me to just let go and fall into the blackness that was threatening to overwhelm me.

But if I did that, if I gave Dawson a second of opportunity, he’d throw his own magic at me, and I didn’t have the strength to ward him off. Not now. So I gritted my teeth, pushed the pain away, and kept hammering at the stone. Bringing the ceiling down might be the last thing I’d ever do, but the fucker was going to fall.

Crack! Crack-crack!

It started to work. A large stalactite broke off from the ceiling. It plummeted down like a knife and speared one of the giants in his shoulder. He howled in pain and fell to the cavern floor. Crimson blood splashed everywhere, and the stone underneath my feet took on a darker vibration.

Dawson’s head snapped around at the giant’s screams. Sloppy, sloppy of him to get distracted like that.

I kept working. Ice, stone. Chisel, hammer.

Another second passed. Another piece of the roof broke off, this time above Dawson’s head. His Stone magic gave him enough of a warning for him to leap forward to get out of its way. The dwarf hit the ground hard.

It didn’t even daze him.

“Kill her!” Dawson screamed at the other giant even as he scrambled to his feet. “Kill her before she collapses the whole ceiling—”

Too late.

I felt a weakness in the stone, a little sliver of vulnerability caused by years of water seeping into it. I gathered my strength a final time and forced all the magic I had left into that pocket of air. It wasn’t as wide as a needle, but it was big enough.

CRACK!
