Goldenthorn is a plant that cannot be found for one hundred miles south of the island of Tar Valon. Goldenthorn seeds were found on the saddlecloth of Zerah Dacan, leading her to confess to Seaine Herimon and Pevara Tazanovni that while she did ride down the bank of the Erinin to the village of Jualdhe, she did not actually begin her journey to Tar Valon from the north as she had implied.
