Captain Lissa Ashkevron was the daughter of Lord Withen and Lady Treesa Ashkevron of Forst Reach, and was Herald-Mage Vanyel's older sister. She was described in Magic's Promise as being a "careless, untidy hoyden" as a child who grew into a "naive swordswoman" fostered to Lord Trevor Corey. She accepted a commission in the Guard, and began her rise through the ranks. By the reign of King Randale, she was a full Captain. She was described as a "hatchet-faced woman" with her long brown hair "braided and coiled atop her head with... military precision." (Magic's Promise) She shared the 'Ashkevron nose' with her father and her aunt Herald-Mage Savil, joking that she had to go into the Guard as she wasn't pretty enough for a marriage offer.
As a child, Lissa was Vanyel's protector and mostly raised him. Their close relationship continued into adulthood.
