The sage does not mask the reek of illness and brackish water. It does nothing against the cold in here. Cold that is bone-cracking. Skin-splitting. Nor does the sage have any effect on the darkness, darkness so complete it sucks you under like a riptide, pressing the air out of your lungs and teasing nightmares from your imagination. The sage does not keep me from seeing stone walls everywhere I look, rough and gouged surfaces, like meat clawed from an animal.

There is no forgetting where we are. No amount of good smell can take my mind off this cold, stale grave, or the Aether that’s put us here by destroying the world outside.

I look around me, at the Dweller cavern where I am stuck helping Molly. This place is the most desperate of all.

“Help me,” someone rasps behind me.

“Water,” moans another voice off in the shadows.

The sounds of the Dwellers wheezing and moaning have not ceased since I arrived.

They are sick. Every one of them is struggling to survive out here, out of their home, the Dweller Pod.

I kneel by a young Dweller girl wrapped in wool blankets. She is around my sister’s age, eight, and has a complexion as gray as ash. Her eyes are rolling back with fever and she looks a little monstrous, but I can’t make myself care. My sister has been back less than a day. I should be with Clara instead of this stranger.

Seeing her sorry condition, I don’t even bother trying to give her water. If I do, it’ll just run down the side of her face, like it did for the last three people before her. So I stand and move on to the next Dweller.

“Everything all right, Brooke?” Molly calls from across the cavern.

I stop mid-stride, the jug sloshing a few drops onto my hand. “Yes, Molly. Everything’s great.” I’m sure my disgust for the Dwellers is apparent on my face. “Just trying to figure out which one of them looks the worst. It’s not easy to do.”

Twelve hours ago, the Moles arrived on a ship with Perry and his new toy, Aria. The Dwellers were forty-some in number. None has succumbed to illness yet and died, as far as I know. When they first saw us, every one of them looked terrified, like they expected us to roast them alive for supper. I enjoyed that moment.

Not even an hour later, the first Dwellers fell ill with fever. And then it was like an avalanche of illness as they dropped off, one after another, until they were all teetering on the edge of consciousness. Molly had them brought back here, to this isolated cavern in the deeper recesses of the cave, to sweat and moan and fight for their lives.
