Changes

'''Lord Berossus''' was an [[Iron Warrior]] [[Chaos Dreadnought]] who, as of late [[M41]] was also the [[Warsmith]] of an Iron Warriors [[Grand Company]] based on the planet [[Medrengard]].{{Fn|1a}}

An officer of the original Iron Warriors [[Space Marine Legion|Legion]], Berossus received his most grievous battle wound (prior to his interment) during the Legion's famous campaign against the [[Black Judges]], when he was caught alone by a dozen of the Judges' Accusators, who rent his body into pieces with their [[Chain Hammer|chain gavel]]s. Although the [[Space Marine Legion|Legion]]'s [[Apothecaries]] were able to revive him, the pain of his wounds always stayed with him, as did the humiliation at being taken off-guard by such relatively minor foes{{Fn|3}}

By the time of the [[Horus Heresy]] Berossus had risen to the rank of [[Space Marine Captain|Captain]] of the 2nd [[Grand Company]]{{Fn|2a}}. When the Iron Warriors were tasked to eliminate the [[Imperial Fists]] battle fleet marooned in the [[Phall system]], Berossus eagerly volunteered to command the fleet, but [[Perturabo]] overruled him, insisting on taking command himself.{{Fn|2b}}

Berossus was later entombed in a [[Dreadnought]] chassis. The fact that he had been crippled by a blow from his own gene-father, rather than in battle, caused a corrosive bitterness that slowly drove him mad.{{Fn|3}} He later appeared during the muster of traitor forces on [[Ullanor]] in preparation for the [[Siege of Terra]].{{Fn|4}} He took part in the [[Siege of Terra]], and while now a minor line officer still led Iron Warriors in the attack on the [[Lion's Gate Spaceport]].{{Fn|5}}

In [[M41]], Berossus and Warsmith [[Toramino]] were embroiled in a dispute with Lord [[Honsou]], who had [[Siege of Hydra Cordatus|recently won]] a prize of stolen [[gene-seed]] from an [[Adeptus Mechanicus]] facility on the planet [[Hydra Cordatus]]. Lord Honsou reneged on a promise made by [[Barban Falk|his predecessor]] to share the geneseed with his fellow Warsmiths, leading to civil war amongst the Iron Warriors.{{Fn|1a}} Lord Toramino and Lord Berossus went on to besiege Honsou's fortress, [[Khalan-Ghol]], for many months; Berossus bore the brunt of the fighting and lost thousands of soldiers.{{citethis}}

Eventually Berossus met Honsou in battle during the latter stages of the war, where he almost killed Honsou with a [[Assault Drill|siege drill]]. However, Honsou's [[Daemonhost]] bodyguard [[Onyx (Iron Warriors)|Onyx]] managed to inflict enough damage to Berossus's dreadnought form. His sarcophagus was opened by Housou, who proceeded to rip Berossus's head from the [[Mind Impulse Unit]] of the dreadnought and crush it for all to see. Berossus's troops then defected to Honsou shortly after his death.{{Fn|1c}}

Although the exact chassis make used by Berossus is unknown, the publication of [[Dead Sky, Black Sun]] allows to infer it was most likely a [[Castraferrum Dreadnought]] pattern.

This chassis had been heavily modified over the millennia since the Horus Heresy, stated to have a “leering skull-faced sarcophagus” with a bronze [[vox-caster]]. Its leg assembly had been substantially widened and strengthened to support heavy breaching equipment such as a piston driven [[siege hammer]] and an [[assault drill]] ringed with several heavy caliber cannons. Mounted on his back were four thick iron arms ending in a variety of picks, blades, claws, and heavy gauge breachers.
