“You know better than anyone how I was born with a gift. All that natural talent, and yet you still want me to defer to everyone else. It's not my fault they work twice as hard and only end up half as good! I mean, I'm risking my life out here too, you know!”
Delthea is the descendant of a powerful mage and holds great talent in magic, more so than her older brother Luthier.
A Duma Faithful necromancer Tatarrah kidnapped Delthea and brainwashed her into being his Witch servant (in Echoes, it's implied that it was Slayde who gave the information to the Duma Faithful on where she lived). Luthier asks Alm and the Deliverance to help him save his sister. They encounter Tatarrah and kill him, freeing her from the necromancer's control. Confused and wondering where her brother is, she flees the battlefield into the floodgate where she reunites with Luthier and meets Alm and the Deliverance. She joins the army to end the war once and for all. After the war, she voluntarily decides to seal her magic and lives a happy life as an ordinary woman. In Echoes she also marries a nobleman.
