Corinna is Therikles Phobas's daughter and a descendant of one of the first Dragonlords, Rizon Phobas.
Corinna was one of the teenagers lured away by Demetria. During her time at the Mossy Temple, she made friends with Loreus, who helped her escape. Luckily, on her way back to Estoria, she met the Oracle's Chosen and was able to guide them to the temple.
During the rescue of the other teenagers, Alke armed Corinna with her own crossbow (which she has since had decorated with an ornate snake decoration and returned.)
Upon her return to Estoria, having proved her skill in battle, Corinna decided to join the Estorian Guard. She requested that Hippofilius put in a good word for her with Vassos, the Captain of the Estorian Guard; unfortunately, gripped by Lutheria's madness, he did not make a good impression on her behalf. He returned to patch things up the next day, however, successfully smoothing over any issues.
Having shown her skill during her training, Corinna is currently acting as Queen Anora's personal guard.
In the recent Great Games at Mytros she won a mithril medal in Archery.
She led a crew of local Mytrosians to take down a child slavery ring which was controlled by Trellus and Septia, herself taking down Septia.
