Brennus Brennus , also known as Brenn , was an Imperial scholar during the reign of Titus Mede I . He was tasked to gather data from Umbriel before it could be a threat for the Empire . The Emperor awarded him a high military rank despite not being a warrior , days before he left the Imperial City . History . Umbriel Crisis . Brennus and other sorcerers were escorted by imperial soldiers to gather data from Umbriel . As Brennus made his measurements , they were attacked by a party of zombies . They didn ' t know the undead could walk away so far from Umbriel . Captain Falcus ordered his men to retreat south . In their retreat , they came across Mountain Watch . They evacuated the villagers and they marched to Cheydinhal . Brennus wasn ' t used to keeping pace of the march . A girl named Lorcette offered Brennus her sit in a wagon . When they were about half a mile away from the city walls , the undead approached them . The villagers had to abandon everything and run . Once inside the city , Brennus went to the highest spire of the chapel of Arkay to make some measurements . The imperial legionaries and the Cheydinhal guard broke the line of the wormies so that the citizens could scape from the siege . They hold the line for hours before Falcus gave the order to regroup on the Blue Road . Brennus and Mazgar broke away from the group . They headed to the Imperial City , but they were spotted by a zombie scout party . They run away from them , but Brennus began to falter . They came across a farmstead , they barricaded the door and they prepared to hold the ground . When the zombies managed to take down the door , Brennus casted a spell that desintegrated three zombies . They were rescued by Ilver Indarys and Knights of the Thorn . They talked about the evacuation of Cheydinhal to the knights , who offered them horses to travel to the Blue Road . Mazgar and Brennus met with the refugees in the Blue Road . Mazgar was given a field promotion to captain by Commander Prossos . She was sent to explore a hill and make sure it was free of the enemy . Brennus accompanied her during her task . The battle went wrong for the imperial army , so General Takar retreated to the Imperial City . Prossos left Mazgar in charge of the refugees , but she requested him to allow her go to defend the Imperial City . Brennus told Prossos that Mazgar had to escort him . Mazgar thought that Brennus wanted to retreat back to Cheydinhal , but he demanded to come along with her to defend the Imperial City . They crossed Lake Rumare by boat . They were attacked by zombies which emerged from the lake . They landed as soon as they could , the surviving soldiers formed a defence line in the shore . Brennus helped as he could . He fell in with Mazgar to rest while they could . They met up with what was left of the Twelfth Legion . They cleared the gate and set up positions to defend it from another siege . Mazgar and Brennus found themselves on the western flank of the action , where little or no fighting was going on . Yet , Umbriel approached the city from that direction , followed by thousands of zombies . Some zombies poured through the gaps that dead soldiers left . Brennus was severely wounded , so Mazgar and him retreated back until their spine was against the wall . Brennus made a semicircle of blue flame around them . Mazgar told him that he would survive , so Brennus told her to do what she had to do . Just when she was going to end with Brennus ' life , Attrebus destroyed the Ingenium , and all the wormies became lifeless . Mazgar turned around to ask Brennus what had happened , but Brennus was already dead .
