Sora

Sora works for the Black Dragon Clan in Escaflowne. She is of an unknown race and is the last of her kind.

In the movie
The daughter of a priest, Sora possesses a predictive power. Her village, Nail, was destroyed by the Black Dragon Clan and she was taken prisoner by Folken. Her people's belief in the Wing Goddess led them to be destroyed.

Sora calls Hitomi with her song. Soon after, Hitomi is called by Folken as well, and ends up on Gaea.

Sora is seen in several scenes consulting with Folken. Folken asks her to call Hitomi to him so that he can use Hitomi's power as the Wing Goddess to destroy all of Gaea. Sora uses her song to call Hitomi again, and asks her to destroy Gaea and end all suffering. Hitomi does not respond to Sora's call and chooses to stay with Van and the others.

When Folken is killed by Jajuka, Sora appears and tells Hitomi and Van to escape because the castle will crumble. She stays with Folken while the castle falls apart. After Hitomi and Van return to Adom, Hitomi asks Van if he can hear "her [Sora's] song," then returns to Earth.
