She is thin, and wears her golden hair in a bun.
While eavesdropping on Egwene al'Vere, Nynaeve al'Meara and Elayne Trakand in Tel'aran'rhiod, Talva unknowingly sets off one of Egwene's wards. She begins to weave Fire at Egwene when the Amyrlin comes to investigate, but is too slow, and Egwene shields her and binds her in flows of Air instead.
Talva is accidentally killed by Alviarin Freidhen, who suddenly appears and throws a jet of Fire at Egwene. When Egwene disappears to avoid the flow, Talva is left in the path of the weave and is incinerated, screaming as her flesh burns. Because she dies in the World of Dreams, she also dies in real life.
