Tuva

Tuva is a noblewoman from Arad Doman (TPoD, Ch. 12; CoT, Prologue).
Nazran, the courier of Graendal's forged message, is supposed to tell Lord Ituralde how he received the letter: King Alsalam sent Lady Tuva as courier, but she was attacked by a Gray Man and died of her wounds while giving the letter to Nazran (TPoD, Ch. 12).
Rodel Ituralde wonders why the Shadow would want to stop the message from reaching him (CoT, Prologue).
Although it is never mentioned, it is safe to say the Lady Tuva really is dead, because the supposed message from the King and Nazran's story would not be believable if she was still alive.
