Marines Mordant

The Marines Mordant was a Loyalist Space Marine Chapter of unknown Founding and a Successor Chapter of the Ultramarines raised in the 35th Millenium. Its Chapter planet is the Mining World of Vitrea Mundi located in the Absinthia System. The Chapter was obligated to undergo a one-hundred-year penitent Crusade through the Tempest Hippocrene in recompense for some unknown offence or dishonour. In the last years of the 41st Millennium, the Marines Mordant lost two companies in battle with the forces of Hive Fleet Leviathan, as well as suffereing severe damage to its Battle Barge Assiduous.

The Marines Mordant had been tasked alongside their fellow Ultramarines Successor Chapters the Crimson Consuls, Vindicators, and the Nova Legion with guarding the rimward frontiers of the Maelstrom Zone. However, in late 41st Millennium, all four Chapters were destroyed in sudden systematic attacks on their Chapter homeworlds, through the machinations and using the forces of the Alpha Legion Chaos Lord Quetzel Carthach.

Notable Campaigns

 * Volvox Wars (Unknown Date) - Facing a new wave of expansion from the Ork Empire of Octavius, the Marines Mordant were called upon to fight back against the Orks.

Chapter Fleet

 * Assiduous (Battle Barge) - The Assiduous was one of the most venerable vessel in the Chapter's fleet and has known many moments of glory, one of them being the destruction of the dreaded Despoiler-class Battleship, the Sacrilegionary. The Assiduous was severely damaged in battle against the Tyranid Bio-ships of Hive Fleet Leviathan. While still undergoing repairs in Vitrea Mundi's orbital docks, the Battle Barge was boarded by the Alpha Legion Warband known as The Redacted and their Cultist followers of the Seventh Sons which broke through all opposition and sabotaged the Assiduous.
