Marines Mordant - Notable Marines Mordant: Chapter Master Tarro Pallidax - Tarro Pallidax was the last Chapter Master of the Marines Mordant. In his youth, Pallidax went toe-to-toe with the grim leader of the Octarian Empire, the Overfiend of Octarius himself, and slew him, but not before his opponent smashed through his helm with his hammer, costing the future Chapter Master his left eye and caving in his skull. Clad in relic Terminator Armour, his hair platinum blond like all the natives of Vitrea Mundi and with a Bionic-eye protruding from his ravaged face, Tarro Pallidax possessed a striking appearance. Pallidax had the misfortune of leading the Marines Mordant through their decline, their strength slowly eroded by the myriad threats emerging from the Maelstrom. Defiant to the end, Pallidax wanted to ensure that the enemy assaulting the Marines Mordant's fortress-monastery, the Bas-Silica, would perish with them. In a desperate attempt to hurt the enemy, Chapter Master Pallidax ordered Captain Sol Ventor -- then at the helm of the venerable Battle Barge Assiduous -- to unleash the power of its Bombardment Cannon directly on the fortress-monastery. Pallidax's final order was for Bas-Silica's Void Shields to be lowered to give the Assiduous an open shot. Though the Assiduous was also destroyed in the battle, it succeeded at levelling the fortress-monastery and killing those within -- both friend and foe.Captain Sol Ventor - The battle-hardened Sol Ventor was the Marines Mordant's Captain of the 4th Company and the Chapter's acting Master of the Fleet. Ventor was the designated heir to Chapter Master Pallidax with whom he had built a strong friendship. Ventor lost an arm when the Tyranids of Hive Fleet Leviathan launched a voracious assault against the Assiduous' bridge. His dedication was such that the captain refused to take the time to replace his lost limb with an augmetic lest his duties go unfulfilled. Although official records state that Captain Ventor was slain in the crash of his flagship, in truth the Assiduous' bridge had already been stormed and taken by the warriors of the Redacted warband under their leader Occam the Untrue. Occam, fearing that Quetzel Carthach intended to betray and kill him, then allowed the Battle Barge to fire at Bas-Silica anyway as per her captain's last orders, annihilating the other Renegade forces on the ground.Master of the Forge Zamander - Master Zamander was the Marines Mordant's final Master of the Forge. During the Fall of Vitrea Mundi, Master Zamander was on the bridge of the Assiduous, monitoring the work of the repair crews on the stricken Battle Barge. Master Zamander died horribly when the Alpha Legion stormed the Battle Barge's bridge. He was burned alive as he sank through the molten metal that had been the bridge's floor after the explosion of the Melta Bombs used by the Chaos Space Marines of the Redacted warband to breach the Assiduous' bridge.Techmarine Arkadii - Brother Arkadii of the Chapter's Armorium was the Techmarine permanently attached to the venerable Battle Barge Assiduous. He was vaporised by the explosions of the Melta Bombs used by the Chaos Space Marines of the Redacted warband to breach the Assiduous' bridge.Company Champion Orthrius - Brother Orthrius' skill with a blade elevated him to Company Champion of the Marines Mordant's 4th Company. Surviving the initial assault of the Alpha Legion on the Assiduous' bridge, Brother Orthrius readied himself to repel the boarders but was treacherously shot in the back by Shipmaster Darrius, revealed as one of the hidden mortal allies of the insidious Heretic Astartes.
