During a confrontation with a platoon of city guards, Jackob used a Necklace of Fireballs to obliterate the threat—along with much of the surrounding area. The move has gone down in whispered notoriety as the Fireball Incident, which resulted in multiple fatalities and the city's imposition of martial law.
Though the act would typically mark him as a citywide enemy, many suspect that the influence of the Cassalanters played a role in escalating the city's response. Jacob has shown no visible regret—only a mild concern about whether anyone looted the corpses afterward.
