“No more than a dozen women in the Tower know what Callandor is, and perhaps as many outside. The High Lords of Tear know, but they never speak of it except when a Lord of the Land is told on being raised. The Sword That Cannot Be Touched is a sa’angreal, girl. Only two more powerful were ever made, and thank the Light, neither of those was ever used. With Callandor in your hands, child, you could level a city at one blow. If you die keeping that out of the Black Ajah’s hands—you, and Egwene, and Elayne, all three—you’ll have done a service to the whole world, and cheap at the price.”
