Built Millennia ago in the legendary ship forges of Mars, the Vengeance of Mars was one of the last ironclad type cruisers to be created in the Segmentum Solar. Although slightly outdated by Imperial Navy standards, not to mentioned armed in a fashion that now longer fits too well with standard naval doctrine, the Ironclad is nonetheless a fearsome ship. Ironclads forego extensive void shield arrays, carrying only enough to fend off minor debris. Instead they place their trust in hugely thick armour and potent, if short ranged weapons. The Vengeance of Mars is armed with a large prow mounted plasma battery, capable of reducing opposing ships to slag as it approaches before charging through enemy lines to unleash its potent broadsides. The onboard barracks holds several thousand naval marines, skilled ship to ship combatants and sufficient shark assault craft to mount potent hit and run attacks.
The Vengeance itself has an enviable history having taken part in some 200 odd campaigns. Painted in designs hundreds of feet high along the port flank of the vessel are depictions of the ship kills it has claimed in this time and along the starboard flank another series of depictions of the ships it has captured. Its crowning moment was the spectacular destruction of the Chaos battleship, the Ark of Lost Souls, during the Battle of MacDuff’s Folly. Arriving late on the scene with its attendant trio of escorts, the Vengeance had the apparent misfortune to exit the Empyrean on the wrong side of a Chaos fleet that had engaged Imperial forces. The captain, in a mix of daring and devotional fervour order all ahead full at the centre of the chaos lines. Bearing down on the Chaos flagship, the Vengeance’s escorts were quickly ripped to shreds. Chaos batteries, bombers and assault craft hammered the Vengeance but due to her thick armour (and the lack of any rear facing lances) the vengeances closed the distance. Finally getting within range of the Chaos battleship, with fire pouring out of multiple hull breaches and enemy boarding parties engaged in furious close combat with the naval marines onboard, the Vengeance opened fire with her forward plasma batteries, melting through the chaos warships armour and burning into her plasma reactor setting off a chain of explosions that tore the ship apart end to end. Sailing through the wreckage the Vengeance opened fire with her broadsides, raking the battleships battlegroup and doing enough damage that the chaos fleet decided to flee rather than fight on. Although she spent years in dock undergoing repairs, the ship won such honour in that battle that the Vengeance was assured a place of pride in fleet operations for centuries to come. Stories of that intense battle and of many other knife edge victories have become legend amongst the crew and the stories become more grand and heroic with each generation.

The infamous Cardinal Moncada was a low ranking member of the Eclessiarchy originally from Scintilla. He was posted to a remote feudal world and found the imperial cult there weak and flabby. Disgusted by its lack of fervour and intensity he set about reforming it from the inside. He soon gathered a large following of believers, people down on their luck and energised by his fiery preaching. He moved rapidly through the ranks of the church, becoming a local bishop, then a planetary archbishop, responsible for the spiritual safety of millions of his followers. His fame grew and redemptionists flocked to his banner. He began to turn his followers against the traditional foes of the Imperium, mutants, heretics, xenos and a new category, traitors. This last category Moncada himself defined as one insufficiently faithful to the Emperor who damages the spiritual health of mankind. Many early traitors just happened to be rival churchmen and nobles that stood in Moncadas way. Moncada by this point was already under the attention of the inquisition and the larger off world church. The act that finally ended his career was an attack by his followers on a neighbouring agriworld. His followers purchased transportation on free captain ships and when they arrived on the agriworld, immediately set about preaching, burning traitors and moving against the powers that be. When the planetary governors palace was stormed and he was killed (reputedly by Moncada himself), the inquisition stepped in and sent in the Imperial Guard. The resulting war was short but brutal, unable to match the skill, resources or equipment of the guard, Moncada’s forces were none the less too brave to surrender and the guard was forced to kill them all. All that is, except the Cardinal himself and his personal bodyguard of 20,000 redemptionists. This army captured one of the transports that had brought them to the world and fled. Pursued by a squadron of naval destroyers, they ran and hid, always on the move until finally they ran the gauntlet of the Maw, arriving in Footfall badly damaged and under supplied.
The rogue traders of Footfall were canny enough not to let the Cardinal (as he was now calling himself) or his followers dock at the station but they did allow him to conduct repairs and buy supplies.
After this, the Cardinal left and has only been seen a few times since. His stolen transport ship, The Spear of Destiny, has become somewhat of a pirate vessel, its favourite tactic to pretend to be crippled in some regard, then when ships investigate, to ram them and board with thousands of crazed fanatics. It has been speculated that the Cardinal must be working from a base of operations somewhere, maybe a habitable planet as he is rarely seen to resupply in port. Whatever the case Moncada clearly has no problems recruiting still, and no compunction against raiding human ships.
The spear of Destiny itself is a large vagabond type transport, unarmed but filled with boarding craft and troops. The vessel was originally a dark green but is slowly being repainted red (rumour goes that they use the blood of their victims to do this). Extra armour has been welded over vulnerable locations and the ship has added thrusters to give it a bit more push when ramming.

The Panopticon of the Void is a very high tech ship produced to the specifications of a legend in ship design, Magos Damian Crozius of Thule. The ship was initially designed as a naval scout vessel, pressing ahead of a fleet and using its extremely powerful sensor arrays to detect ambushes, enemies and celestial phenomena. The ships weapons are all long range and designed to allow a hit and run style of combat, allowing the ship to find a weakness in an enemy fleet deployment with its sensors, attack it from range with its laser batteries and then escape before any response could be mounted.
This particular iteration of the design never made it to the Naval fleet. It was in drydock undergoing its naming ceremony when its home world was attacked by a large fleet of ork raiders. The ship was heavily damaged and the navy wrote it off as future salvage. Rogue Trader Bjorn Winterscale however had different plans. Assessing the ships damage he was impressed by the solid construction and advanced systems and managed to apply enough pressure to the planets governor to be allowed to requisition it.
Five years of refits brought the ship to a fully functioning state again and the ship was good as new. Winterscale took the ship into the Koronus expanse to act as the eyes and ears of his personal fleet when needed and to act as an excellent exploration and exploitation vessel the rest of the time. Today, the ship is feared throughout the expanse as a deadly fighter, capable of destroying anything smaller than it and fleeing anything larger. Many enemies that could destroy it never know it is there as the ships powerful sensors can detect a foe in time to allow the Panopticon to avoid that foe.

The Iteration of truth was once a warship of the Thulian fleet under the captaincy of Admiral-Magos Johannes Toth. Toth was an excellent military leader and a respected Magos with a long and glorious history of service in the Thulian cult. To this day it is not known what the trigger for his sudden apostasy and tech heresy was, but it is believed by senior figures in the Cult of Thule that in the course of fighting off what was thought to be a xenos warship, near the rifts of Hecaton, he discovered something, perhaps xenos technology, perhaps archeotech or perhaps even some kind of chaos artefact. All that is known is that several hours after boarding the enemy ship and with no warning, the Iteration fired upon its two escort vessels, catching them unawares. Once crippled these vessels were boarded by murder servitors and howling skitarii. There were no survivors.
The Iteration disappeared. The remains of the escorts were found a few years later by members of the Cult of Thule and what little is known about the betrayal was pulled together through painstaking forensic analysis.
Since then the Iteration has become something of a paradox. At times it will attack other ships, refusing to answer hails or give demands. On other occasions it has towed damaged vessels to safety, helped make repairs and replenished supplies then gone on its way. It turns up at footfall every now and then and stays long enough only to resupply before leaving before a Thulian response can be mounted. While in dock it does a good trade in heretek devices, advanced technology and ship repairs. Many rogue traders look forward to meeting the vessel in port and fear meeting it in space.
As a Mechanicus ship the Iteration is extremely capable. Its weapons are powerful, it has deadly boarding capabilities and it is fast, deadly and tough. It known to have boarded and captured several ships in the expanse, no one knows what happens to these vessels.

A true ship of war, the Visions of Madness was once the Golden Hawk (so named because its armoured prow resembles a huge golden aquila) a distinguished and deadly naval vessel. While on deep patrol with its escort squadron it was lost with all hands. What is not so well known is that the ship had long harboured a large and secretive chaos cult amongst its officer class. The ship had traditionally been staffed with officers from a small group of Malfian noble houses and when these houses began to worship the dark gods in an effort to gain an edge on their rivals, so do did the young officers they sent to crew the Golden Hawk. This spiritual malaise continued for centuries undetected as slowly the officers, in a bid to make their lives easier inducted families of crewmen onboard the ship into various small cults ultimately controlled by themselves. This all could have continued on for centuries more but the cults had gained a little too much notoriety amongst their naval peers. Eventually naval intelligence took an interest and the officers decided to mutiny rather than face charges and execution. After taking control of their ship they managed to board and capture two of their escorts, blasting the third into pieces and bombarding the wreck. After that the ship disappeared into the Koronus expanse. The resulting inquisition investigation has led to a series of high profile executions on Malfi but the ship and its crew were never recovered. It is believed that the ship now hunts throughout the Expanse, calling in at xeno and heathen ports to resupply. With the formidable strength of a military cruiser and a pair of escorts, there are few forces in the expanse that are capable of besting it in battle. Rumours linking it to larger chaos warbands are unconfirmed but it would certainly be the feather in the cap for any warlord that acquired them.
