Varro Tigurius - Battle-Brother: Though in the early years of his service to the Chapter Tigurius' ability roused a terrible suspicion among his battle-brothers, even for a Librarian, over time the scepticism he engendered subsided, for the worth of his abilities was clear for all to see. When deployed to a war zone, Tigurius was able to provide a tactical insight to the Captains and Sergeants who lay out the strategies for their warriors. In the Altor Crusade Tigurius forewarned the Scouts of the 10th Company of a successive series of ambushes planned by Eldar Pathfinders. His warnings, initially heeded with a degree of scepticism, doubtless saved dozens of lives -- rather than leading their recruits into deadly traps, the Sergeants instead called in fire support from the Chapter's Stormtalons, which duly turned the awaiting Eldar snipers into grisly corpses with their assault cannon fire. He also warned Captain Agemman to arrive several hours early for the armistice talks with the Eldar Autarch. When the Eldar general arrived with his entourage, he found the jungle foliage that had concealed squads of waiting Striking Scorpions burned to stubble by Agemman's Land Raider Redeemer, Infernal Retribution, and the Captain waiting with his relic blade drawn.Later, serving the 5th Company, Tigurius led a strike force against the Seven Sorcerers of Harka, a coven of Chaos Space Marines who held an entire planet in their thrall. Although Tigurius' visions did not reveal to Tigurius the nature of his foes, he prepared carefully, working with the Chapter artificers to modify his psychic hood ahead of the mission. At first the assault on Harka went well, with the Space Marines storming the Seven's stronghold and fighting their way down the crowded streets. Fighting with typical Ultramarines finesse, the Tactical Squads fought through the hundreds of treacherous humans who had thrown their lot in with the Seven. Faithless renegades and degenerate mutants died by the hundred as Tigurius and his Space Marines stalked through the ruins of Harka searching for the foe.Thinking to thwart the Ultramarines, the Seven Sorcerers attacked them as they were embroiled slaughtering a horde of wretched scum armed only with flintlock weapons and improvised clubs. By contrast to their decrepit minions, the Seven were veritable gods of war -- clad in glossy black power armour and surrounded by crackling nimbuses of Warp energy, they stalked upon the Ultramarines, unleashing a bow-wave of power that blasted hundreds of traitors and a dozen Space Marines from their feet. Only Tigurius felt the shifting power of the Warp at work, as the Seven channelled their sorcery. Warily he turned to face this new foe, raising his force staff as bodies -- friend and foe -- around him began to explode from within like fleshy grenades. Here a Chaos-worshipping traitor blasted apart in a welter of gristle and blood, there a mutant burst into a gory mist as if shot by a cannon. Battle-brother Sydes died before he even perceived his attackers, segments of his armour clattering around as his body erupted. The Seven pointed as one, an indiscriminate movement, and with every gesture there was another grim victim.Tigurius halted their advance with a wall of balefire that seared out from his force staff -- a blazing conflagration that scorched a path through the prone bodies of their mortal followers to embroil them in flames. As their Librarian fought a psychic duel, Sergeant Orestes and a handful of Tactical Marines scrambled to their feet to protect him, holding back the fanatical throng. One Space Marine Librarian against seven Chaos Sorcerers were slim odds, and yet Tigurius did not quail. Screaming in rage he poured more of his soul into his attack. The flames danced around his foes, lapping at the energy that glowed around the Chaos Space Marines. Tigurius' face contorted in pain, and the flames blazed white hot. The psychic hood upon his shoulders radiated with the power coursing through it, and Tigurius' eyes ran bloodshot as the rockcrete roadway began to bubble and melt. As the Seven writhed within the flames, Tigurius' shout of rage became a hoarse shriek and the Seven were burned to death, one by one, slowly at first and then faster as their power died, the smouldering armoured bodies of the seven clattering to fall upon the ground and sink into the boiling road.
