She had a pleasant-face with brown eyes.
Elza was not particularly strong in the One Power. Her level of strength is described by "The Wheel of Time Companion" as 25(13) which is a middle level in Aes Sedai hierarchy. With this level of strength she was unable to open alone a suitable gateway to Travel.
She was from Andor.
Oath to the DragonEdit
She was taken prisoner by the Asha'man after the battle at Dumai's Wells but begged to be allowed to swear fealty to the Dragon Reborn. She appeared somewhat fanatical in her following of Rand. Elza swore fealty to Rand after saying she realized that it was crucial that al'Thor make it to the Last Battle, so her true master, the Dark One, can defeat him there. This might suggest the oath she gave was the result of the Compulsion Verin Mathwin used on some of the Aes Sedai captives from Dumai's Wells, in order to make sure they all swear fealty.
She Traveled with Cadsuane Melaidhrin to Far Madding to track down Rand. During the Battle near Shadar Logoth, under Cadsuane's direction, she linked with Jahar Narishma and Merise Haindehl to defend Rand against an attack by the Forsaken. During the attack, she killed Corlan Dashiva, who she thought was a mere Asha'man, not knowing he was actually the Forsaken Osan'gar.
The group Traveled to Algarin Pendaloan's house in Tear, where Rand recovers after cleansing saidin. Elza stood guard over him and had become very protective of him, even using physical means to stop people from seeing him. She met with her Warder, Fearil, when he arrived in Tear and didn't seem shy on inflicting pain on him. She had decided that some people in the group are going to have to die soon.
She participated in the battle with the Trollocs when they attacked the manor. After the battle, she escorted Davram Bashere to Rand and then helped to burn all the dead bodies away. She watched Rand's meeting with the supposed highest ranking Seanchan on the continent from a distance and Traveled in as back up when it was revealed that the Daughter of the Nine Moons is actually Semirhage, who was taken captive.
She escorted Rand when he went to meet Harine din Togara Two Winds.
She was there when Semirhage was freed by Shaidar Haran. She handed the Domination Band to Semirhage and mentioned that there was Compulsion in her mind and that Semirhage was to remove it. Semirhage and Elza ensnared Rand with the male a'dam, from which he escaped by drawing from the True Power, killing both women with balefire.
