In 430, while working on a mission to find Aducath, Zem was arrested by the Marali Vanguard, under the accusation of trying to assassinate the Vanguard's own Captain Boric. At the time, the Mirith Vanguard made an attempt to stop the imprisonment, claiming the mercenary's innocence. Mirith, also interested in hiring Zem again to search for the Royal Sceptre that had been stolen not long before, demanded that Marali would give their prisoner a fair and public trial. To the date, that has not happened.
