Serenia Latar was an Aes Sedai of the Gray Ajah. She was raised to the Amyrlin Seat in the year 276 NE, and held the position until her death in 306 NE. She was Comarra Zepava's successor, and Doniella Alievin's predecessor (TWoRJTWoT, Ch. 24).
Serenia Latar is the only Amyrlin Seat the Whitecloaks have ever hanged, but she was already dead when they did so. A picture of her being raised on the scaffold hangs in the Dome of Truth (LoC, Ch. 31).
"Finally he saw a tall, graying man studying one of the paintings, Serenia Latar being raised on the scaffold, the only Amyrlin the Children had ever managed to hang. She had been dead already, of course, live witches being somewhat hard to hang, but that was beside the point. Six hundred and ninety-three years ago, justice had been done according to the law." (Eamon Valda; Lord of Chaos, Chapter 31)
