Revenge of the Forsaken Elf Queen

Freya, half-elf born with peerless magical power, hides her abilities to honor her mother's last wish and marries ordinary husband Elliot. He falls for Olivia and betrays her to help Olivia win fame; his family seizes Freya's property and humiliates her. On the battlefield, Freya displays astonishing talent and exposes the truth: Olivia's merits are built on slaughtering innocents and forging fake treaties. Freya also discovers the Windsor family massacre was part of the same conspiracy.
