Doomseer is the Seanchan term for someone who has Min's ability to see auras and images around people giving a glimpse of their future. Before Min, the Crystal Throne hadn't had one in over three hundred years. When the Seanchan realize what she can do, the guards back away from her and the one who had touched her removes his gauntlets and wipes his and as if to clean it. The Seanchan hold such a person in high reverence, partly because of their own regard for omens.
