Over the years she bore many eggs, but gave only one to the Dragon Riders, which hatched for Eragon Bromsson. It is also known that her mate was a Rider's dragon named Iormúngr. She perished in the Fall of the Dragon Riders.
When asked what color Vervada and Iormúngr were in a Q&A session, Christopher Paolini said, "I've yet to decide that, actually, but with a name like Vervada, I wouldn't be surprised if Saphira's mother was crimson."
Vervada's crimson color would be lighter in tone and hue than the "ruby red" color of another red dragon in the series, Thorn.
