The Last Days of Ilam
Red Dragon in service to Lethris Ulshar
Xecorra Darkfire is a 6th generation red dragon. She was captured by a fire giant who intended to skin her. Xecorra was saved by the Velvet Dagger and Lethris Ulshar and pledged her service to Lethris.
Such a debt is not a known dragon custom, however Xecorra sympathized with Lethris. Xecorra herself is also an outcast, she was driven from Red Mountain after she failed to bear any eggs.
