Elvira is the twin sister of Faro, a Mer girl, Conor's former love interest, and a major supporting character in the Ingo series. During the Crossing of Ingo, Elvira was touched by her Atka and now believes that she can only truly be happy if she lives in the North. Before this, Elvira was training as a healer.

Unlike her brother Faro, Elvira is wholly Mer.
