A minor edit on the previous article on the Alpha Legion and their exploits as well as the Luna Wolves' name change. Sorry for forgetting all about them >_<
Magnus attempts to
warn the Emperor by projecting his ethereal body across space and into Terra via the Eldar Webway Gates. This results in the Emperor's in-construction man-made Webway Gate to be breached with demons from the Warp. Grieved with what he has done, Magnus leaves Terra without telling the Emperor of Horus' perfidy.
Perturabo loses control
of Olympia, his homeworld, the first Primarch to do so. Horus extends his hand in friendship. Horus also brings Kelbor-Hal, leader of the Mechanicum of Mars - to his side.
Fulgrim's expeditionary fleet
joins the Warmaster's, briefly toying with the idea of firing on the Warmaster's fleet, Fulgrim eventually decides against it, and boards the Vengeful Spirit, Horus' flagship.
Horus reveals his
plans for rebellion to Fulgrim, and brings him to the fold. Fulgrim vows to bring Ferrus Manus and the Iron Hands to Horus' banner. Leman Russ is ordered to bring the Emperor's sanction on Prospero.
Leman Russ' orders
were countermanded and changed by Horus Lupercal. Magnus is no longer needed to return to Terra for trial. The Primarch and his Legion is to be exterminated.
Meanwhile, four Legions, the Sons of Horus, World Eaters, Death Guard and Emperor's Children gather in the Istvan system to quell a rebel world.
Ferrus Manus throws
Fulgrim's treacheries back in his face. The Primarchs duel, leaving Ferrus unconscious and the Iron Hand's terminator elite, the Morlocks, incapacitated. Units that were not expected to join the Warmaster in his rebellion are dropped into Istvan and virus bombed. Captain Saul Tarvitz of the Emperor's Children gets the warning to the loyalists in time to seek cover.
Captain Nathaniel Garro
receives the warning aboard the frigate Eisenstein, and escapes, bringing the warning to Terra. Lost in the Warp, they were eventually found by Rogal Dorn and his Imperial Fists Legion.
Angron disobeys orders
and takes his World Eaters down to the battle to finish off the loyalists. Initially angered by Angron's lack of respect, he orders his warriors down as well, with the purpose of blooding his Legions for the coming conflict.
Having won the
battle thanks to Lucius of the Emperor's Children's treachery, The 4 Legions entrench themselves in the Urgall Depression of Istvan V in preparation for the inevitable retribution from the Imperium.
Rogal Dorn orders
7 Legions alongside his own Imperial Fists - the Word Bearers, Night Lords, Salamanders, Iron Hands, Raven Guard, Iron Warriors and Alpha Legion towards Istvan to bring the Warmaster to justice. The Imperial Fists were lost in the warp.
The Heresy begins
- The second wave of Night Lords, Word Bearers, Iron Warriors and Alpha Legion turn their guns on the Iron Hands, Raven Guard and Salamanders as they withdraw to rearm and repair. This event is later known as the Dropsite Massacre. Ferrus Manus is killed by Fulgrim.
The Battle of Prospero
commences. Leman Russ' Space Wolves, augmented by the Silent Sisterhood face down the Thousand Sons Space Marine Legion and the Prosperine Spireguard. The Thousand Sons escape with the help of Tzeentch.
Corax manages to
escape and heads for Terra to rebuild his shattered Legion. Alpharius allows them to escape the orbital cordon with the intention of stealing whatever secrets the Emperor may bestow upon Corax.
Magnus the Red
contacts Horus, presumably to join his rebellion. The Night Lords leave for the Thramas system to engage the Dark Angels, the Word Bearers engage the Blood Angels in Signus Prime, and the Ultramarines in Calth.
Forgebreaker, the hammer
forged under mount Narodnya by Fulgrim and wielded by Ferrus Manus is given to Perturabo as a token of friendship. Corax is granted the secrets of the Primarch Project to create a new breed of super-astartes.
It is a mystery as to why the Emperor didn't create this breed of super-astartes from the beginning but it turns out that was a sound decision. Also the super-astartes is made by combining the best of every Primarch, and the Emperor didn't want all the Legions to have the same skill set, as he wanted to fashion different Legions for different uses.
The first super-astartes
is successfully created. Omegon orders his operatives to sabotage the gene-project and claim it for the Alpha Legion. They are successful. Kelbor-Hal declares for the Warmaster, and the Mechanicum is plunged into civil war.
Captain Nathaniel Garro travels to the now-empty Istvan to find Captain Garviel Loken to add to his Avengers
team of pure-hearted vigilant warriors, the forerunners of the Inquisition.
Siege of Terra
Before Gregor Eisenhorn, there was Nathaniel Garro.
finally begins after years of fighting, intrigue, espionage and counter espionage. On the side of the loyalists are the Blood Angels, White Scars and Imperial Fists, on the traitor's side - the Sons of Horus, Thousand Sons, Emperor's Children, Death Guard, and World Eaters.
Aaron Dembski-Bowden's Night Lords series places the VIII Legion on Terra during the siege. This may be a canon conflict, as other sources cite them as 'on a genocidal crusade in the galactic east'.
The loyalists are
steadily pushed back deeper into the Imperial Palace with the Emperor still busy staving off the demons that assail his artificial Webway. Eventually, the impending arrival of the Dark Angels, Space Wolves and Ultramarines Legions threaten to break the siege.
Horus decides to
take a gamble and allows the Emperor's forces to teleport into the Vengeful Spirit. The Emperor takes the bait. However, it was Sanguinius who faced Horus first. Foreseeing that this was where he met his end, Sanguinius rejected Horus' offer to join the Dark Gods.
Sanguinius dies by
the Warmaster's claws, but not before leaving a chink in Horus' armour. The Emperor finally arrives to face down Horus, promptly gets grievously wounded for holding back.
Ollanius Pius, an
Imperial Army trooper enters the scene. Horus flays him with but a look. the Emperor finally realizes that Horus has fallen too far to be saved and unleashes a psychic attack so great it destroyed Horus' soul.
We're finished! Well ok, we're just about done. This series will run for two more editions, the next one will talk about the aftermath of the Heresy and the last one will talk about miscellaneous things I decided to omit for being too trivial, such as the Primarch's psychic powers, the Eye of Terra, etc as well as canon conflicts. However, if there is anything else you would like to see fleshed out, explained or mentioned, do let me know and I'll do my best to oblige.
