[Once she's assured that the guard doesn't need healing, Elayne follows the woman over to the sacks of grain, only to be brought up short by the gesture. Not to be put off, she kneels, inspecting the dark puddle on the floor more closely.]

I've seen it too. I woke up in a cage in a cart being brought to the city. There were sacks of grain, stained dark like this. One of the farmers in the cage seemed to go mad, an his eyes were leaking dark water... [The same dark water she found in the abandoned baths. It's everywhere here, it seems.

She pulls out the vial with the sample of dark water she took from the baths, comparing it to the puddle on the floor. It appears to be the same stuff.

Elayne can't help the smug look that crosses her face. So she was right, this woman is familiar with the One Power.]

You're the first person I've met here who knows of the One Power. You can see my weaves, can't you?
