Cinderflare

Cinderflare, although never seen in the series alive, is the dragon that Morgan Lafayette is initially sent out to investigate the disappearance of in Sphere of Power. Her lair showed signs of a struggle and Einar, the guardian left behind, has no idea what happened to her.

Description
There is no description of Cinderflare offered. The only clues are that she was female, as evidenced by her recently-hatched young (eggs were discovered at the scene, which Morgan believed to have been thunder eggs... naturally forming geodes). All of the fey refer to Cinderflare as female, leading further faith in the assumption that she was female.

Offspring
Although there is evidence in Cinderflare's lair to indicate that she had recently hatched an unknown number of offspring, no mention of what happened to the young dragons is mentioned in any of the books. Their whereabouts remain unknown.

Reincarnation
As one of the characteristics of the fey is their ability to reincarnate through the Ether, it is unknown whether Cinderflare will return in another incarnation.
