Helena is Hippofilius' mother who died at the hands of his father, Sydon. Before she died she managed to hide her son from the Titan, knowing that he was prophesied to return the Dragonlords.
Her soul is currently contained inside an amulet, which was gifted to her son by Versi. Now, despite her death, she can contact Hippofilius in his mind and dreams. She recently appeared to him on his birthday to tell him of the ‘fortress’ that Xander Huorath had brought to Thylea that now resides in the Garden of Helios.
Unlike Hippofilius, Helena is a human. She changed her son’s form as a baby to hide him from Sydon: a feat that required a great deal of power.
