"Yet if Valda did try something on his own — "

Siuan cut her off. "He has no more than five hundred men close to Tar Valon, girl. He sent the rest away weeks ago, to cause trouble elsewhere. The Shining Walls held off the Aiel. And Artur Hawkwing, too. Valda will never break into Tar Valon unless the city is already falling apart from the inside." Her voice did not change as she went on. "You very much want me to believe the trouble will come from the Whitecloaks. Why?" There was no gentleness in her eyes.

"Because I want to believe it," Min muttered. She licked her lips and spoke the words she did not want to say. "The silver collar I saw on that one Aes Sedai. Mother, it looked… It looked like one of the collars the… the Seanchan use to… to control women who can channel." Her voice dwindled as Siuan's mouth twisted with distaste.

"Filthy things," the Amyrlin growled. "As well most people don't believe a quarter of what they hear about the Seanchan. But there's more chance of it being the Whitecloaks. If the Seanchan land again, anywhere, I will know it in days by pigeon, and it is a long way from the sea to Tar Valon. If they do reappear, I will have plenty of warning. No, I fear what you see is something far worse than the Seanchan. I fear it can only be the Black Ajah, Only a handful of us know about them, and I don't relish what will happen when the knowledge becomes common, but they are the greatest immediate threat to the Tower."

Min realized she was clutching her skirt so hard that her hands hurt; her mouth was dry as dust. The White Tower had always coldly denied the existence of a hidden Ajah, dedicated to the Dark One. The surest way to anger an Aes Sedai was merely to mention such a thing. For the Amyrlin Seat herself to give the Black Ajah reality so casually made Min's spine turn to ice.
