Tieri was the daughter of Gerraint and Telarien. She was the sole survivor of the Knorth Massacre, sent into hiding in the Ghost Walks of Gothregor by Aerulan at the cost of the latter's life. She was taken care of and hidden by Adiraina, the Ardeth Matriarch. Unknown to others, Gerraint had given Gerridon, Master of Knorth, a contract with Tieri; Gerridon came to her in the Moon Garden, and Tieri bore a son, Kindrie.
