When the Ogier began work on Al'cair'rahienallen, they planted a grove there because nearby, Stedding Tsofu had not yet been rediscovered since the Breaking. Stedding Tsofu was rediscovered only about six hundred years before the present day while Elders were still growing Waygates.
During the quest to regain the stolen Horn of Valere, Verin Mathwin suggests that the group try using the Waygate at Stedding Tsofu, since the one located in Cairhien was found blocked by Machin Shin. Rand, Mat, Perrin, Verin, and the Shienarans arrive at Stedding Tsofu and meet with the elders, but they find the Waygate there also blocked by Machin Shin.
Later still, Rand visits Stedding Tsofu once again to ask the Elders to let him place guards at the Waygate, but Rand's appeal is rejected, with Alar refusing to listen to a human.
