Valinde is described as stout.
Valinde is not very strong in the One Power. Her level of strength is described by "The Wheel of Time Companion" as 33(21) which is an intermediate level in Aes Sedai hierarchy. With this level of strength she is unable to open alone a suitable gateway to Travel.
Valinde was by far the weakest among the Salidar Embassy to the Dragon Reborn and the only one unable to Travel by her own.
According to Min, she was very eager to have Rand drive Sammael out of Illian. Min believes that a promise from Rand to try would have convinced Valinde to swear fealty to him - though Melaine scoffed at that idea.
She is part of the group of Aes Sedai who demand that Rand lift the restrictions he had placed on them. When he refuses, the Aes Sedai leave in a huff.
She tended to side with Romanda Cassin.
