Hennia, often referred to as Hennia the Zain, was a member of the Council of Santhenar; noted for her brilliance, but also for her inability to commit to a single side. Hennia betrayed the Council to Yggur during their escape to the Wharf City and was later present during Maigraith and Thyllan's negotiations, during the Second Battle of Thurkad, as well as their subsequent duel.
