Henry says

Too many knuckles.

Something long lives in the puddles in the cistern. I bought a finger off a man once, said it came out of the water. Gold ring on it, one joint too many. He didn't go back for the rest.

Kate says

Thin as a rake.

There's something in one of the puddles in the cistern. Tall, thin as a rake, and it grips - it gets hold and it doesn't let go. You won't know which puddle until you're in it, love. Look before you dive.

Hollis says

Grows in the wet.

Down in the cistern water something keeps growing - fingers too long, joints it shouldn't have. Only one of the lower puddles holds it; the rest hold the Drowned, or what the Drowned let go of. When it hardens all over, hit it later. Nothing gets through stone.
