Kyra Hawthorne
A member of Marcus' gang hired to find Sinzil's Repose. She joined the group with her husband Gideon Hawthorne. According to Phinneas Boggs, and through visible demonstration, Kyra is a wizard of some skill.
After the confrontation with the party outside Sinzil's tomb, the Hawthornes fled back to Redwall Citadel with all the loot the party had found—including Sinzil's Circlet.
