Eterna's Source

Sery is a Source, born with immense magic but unable to use it. Enslaved for her power, her life is one of abuse and exploitation until one day, everything changes. Veltyen, a sword-mage, rescues her, releasing her from her chains. He takes her to join the mage guild Eterna, where she learns she can help others without being used. As her magic boosts the guild to entirely new levels of power, trouble brews. Other guilds want Sery's power, and they are willing to destroy Eterna to get it. As Sery comes into her own and explores the unique powers of a Source, she makes unexpected innovations that will change society, and life as she knows it.
