In the final moment, one mysterious blazing shot broke up the deadly fight between the two brothers. The final blow was missed, and two lives were spared. Therefore began the journey for redemption and reuniting of the lost souls.

In the year 006.M31 was at the peak of the grotesque tragic event in the Imperium History, the Drop Site Massacre, when the Horus Heresy officially began. The Loyalist Army led by the Iron Hands, the Salamanders, and the Raven Guard Legions confronted the 7 Traitor Legions on the planet Istvaan V.The highlight of the battle was the fight between two generals from the Loyalists and Traitors, Primarch Ferrus Manus and Primarch Fulgrim. Both once dearest brothers fought each other to death. They were severely injured, wounded, and extremely exhausted. Before either of them could finish the final blow, one mysterious blazing shot broke their fight, sending them from the hill onto the ground, where they started the second fight bare fists. Fulgrim was knocked out, and when he gained consciousness, he and Ferrus were saved on the Iron Hands' Strike Destroyer 'Ferrum, which served as the Tenth Legionnaire's commander ship.Fulgrim met Vulkan and several high-ranking officers of the Iron Hands, including First Captain Gabriel Santar, on board the Ferrum. He learned that the Iron Tenth demanded to take their Primarch back to their home world despite being located far away and being chased by the furious traitor forces, expecting the Emperor's Children as the front line. Fulgrim suggested Vulkan and all crews on board to call for aid, Fenris was the nearest place to reach. Leman Russ showed up and handled the EC troop before taking Fulgrim into custody to Terra as Ferrum and all her crews jumped into the warp drive to Medusa.The roads that used to cross passed and merged were broken, and the two unsettled brothers separated ways shortly. Fulgrim was in Terra for not so long before escaping with the help of the Crimson King, through the psyker warp portal specifically created. The Phoenix had arrived on Medusa, where the Gorgon used to land a century ago, and grew up to its ruler and legend of the Medusan people. From here, he began his quest for redemption, bringing his most beloved brother back to life by risking his life to seek help from the Xenos race, Farseer of the Ulthwe.The quest to find Farseer took a month to succeed. Fulgrim and the Eldars successfully woke Ferrus up, only for him to knock his once beloved brother down again.After returning to life, Ferrus followed up with everyone, including Vulkan and Santar, about the current situation. Fireblade was returned to him shortly after he woke up with the details of the event at the Drop Site Massacre and how Fulgrim showed up in his home world. Ferrus received contact from Leman Russ and then he visited himself.Ferrus, the other two Primarchs, and Fulgrim (in the stasis prison capsule) departed to Terra, seeking to meet with their father. Unfortunately, the Emperor had a more important task, and Malcador the Sigilite spoke on his behalf. Finally, The Gorgon came up with a term for reinforcement and supporting units for the war with the Warmaster that he knew he would be back soon. Not only the support he'd got but also the prisoner because the Emperor commanded through Malcador that The Tenth Primarch had to settle with his 'brother' before starting his new campaign against their eldest brother, Horus Lupercal.

Contact

Hello guys, you can call me 'Siri (as in iPhone, it's the same word). I'm a Thai WH40K 'Horus Heresy' fan (and I'm with the Iron Hands because their father is my No.1 on the list) who stepped in half a year ago (approx. August 2023) because of the official canon ship, they're my OTP and they're still together in my headcanon.I'm also a part-time amateur writer who normally publishes original novels online. Sometimes, I write fanfics, and this one is my current project. I plan to translate all the script into English, but it will take a long time as I have to focus on my priority research. Translation isn't my profession, and English is not my mother tongue.However, I'm delighted to meet everyone. If there is anything interesting for you, please feel free to drop by.
