With Obsydia's chaos growing and more kingdoms falling under her control, Runa, Mellypip and their friends scramble to find a way to stop her from discarding her mortal form and claiming their world in the name of her Eternal Father Ahridum and plunging it into a never-ending age of darkness and evil.

The dragons of Rapiveshta are awakened from their long slumber by Obsydia's attempt to steal the egg that holds the unborn dragon who will become the next leader of the dragon clans. The egg is given to Runa's grandfather to protect it. When it hatches, Mellypip finds himself bonded to the baby dragon as her guardian.

As Obsydia reaches the climax of the ritual that will burn away her mortality, Runa, Opaline and Panthara find themselves captured to be used as sacrifices. Will the Gate of Souls claim Runa and Mellypip as the Winged Fey have foreseen? Or will the Fires of Rapiveshta and those chosen to be the Scions of Light be able to save them and their world.
