Elena

Elena was Greil's wife and Ike and Mist's mother.

Before Fire Emblem: Path of Radiance
Once a resident of Daein along with her husband, she did her best to take care of Lillia, a heron laguz and Reyson's older sister, whom Ashnard had captured and imprisoned within a temple. Elena came to be a good friend of Lillia's, and although they shared no common tongue, Lillia was able to eventually give her both Lehran's Medallion and the song of release necessary to release the dark god within it. The ultimate goal was to return the medallion to Serenes Forest, but Elena and Greil spent several years on the run from Daein. For a time, they lived in Gallia, and it was there that she gave birth to her children. Unfortunately, after Greil made the mistake of taking hold of the medallion and going berserk, Elena was impaled by him while attempting to wrestle the medallion from his grasp. Forgiving him with her final words, she then died.

Etymology
A European variant of the Greek name Helen, which means 'torch' or 'corposant.' In Greek mythology Helen is the daughter of Zeus and Leda and the most beautiful woman in the world. Although married to Menelaus of Sparta, she falls in love with Paris, prince of Troy, thus beginning the Trojan war.
