The Court Warrior's Fatal Oath

Wren enters the palace on her master's behalf to assist with heir selection. She discovers First Prince Hugo is hypocritical, while Second Prince Ryan is reserved, so she recommends Ryan in the Imperial Court Chamber. She is framed and imprisoned by Empress Fiona and First Prince Hugo, and sends a distress message. Her master arrives to rescue the emperor, the emperor ousts the corrupt conspirators, and Wren is finally vindicated.
