Armillus Dynat, known as the "Griefbringer" and "Instar-Nine," was a Harrowmaster of the mysterious Alpha Legion during the Great Crusade and Horus Heresy eras in the 30th and early 31st Millennia. Dynat was a feared strike commander since his name came to prominence during the invasion of Paramar V. Known to possess strategic genius, his style of warfare was as intricate as it was unorthodox. Using fast moving, heavily armoured vehicles and close air support, he would split enemy formations apart before crushing them without mercy. Armillus Dynat was an expert duellist and warrior in his own right. Wielding a Thunder Hammer and Power Sword in unison and carrying uncommon wargear such as Venom Spheres and Phosphex Bombs, he was an opponent to be reckoned with.
As with much of his mysterious Legion, little can be said for certain about the origins or character of the Alpha Legion commander known as Armillus Dynat (whose name itself may be an artificial construction using mimetic factors from several different dead Terran dialects meaning approximately "The fallen prince/false prophet who destroys with power"). Pictorial references for this officer is only available thanks to the recordings of Ultramarines -- attached Remembrancers present at the Palcine War Council, where Dynat is recorded as having infamously sparred with First Captain Marius Gage over the conduct of the war after the Ultramarines' repulsed attack during the Battle of Asarna Bay.
Dynat was known to be a formidable strategist with a penchant for unorthodox and highly intricate attack plans often designed to pull apart and maim enemy fortifications before a killing blow was delivered. Armillus was also a master of integrated fast-armour and close air-support tactics. Armillus Dynat is thought to have been a theatre commander during the notorious Tesstra Campaign and the mastermind behind the Oanessi Genocide and the Harrowing of Callista Mundus. His name quickly became infamous during the Horus Heresy as a feared strike commander, beginning with the invasion of Paramar. His ultimate fate is unknown.
