(Note: This is my first Warhammer fanfic. I hope you guys enjoy the story and the journey)
In the vast expanse of the Milky way the Master of Mankind worked on a project that would one day bring a new dawn for all of humanity. The Creation of his "sons" the Primarchs.
Yet due to the insidious whispers of Chaos one of the few that the Emperor completely trusted had betrayed him and destroyed the Geller field generator and protective formations that surrounded the chamber that contains the gestation pods of Humanity's Salvation.
She was Erda. A fellow perpetual and long time companion of the Emperor of mankind and ironically enough the one who's genetic material was used alongside the Emperor's to make the Primarchs, effectively she was their "mother" just as the Emperor were their "Father".
Due to this act the Ruinous powers were able to bring the infants within the Warp but due to the intervention of the Emperor of mankind the Primarchs were instead scattered to different worlds within the Galaxy.
Erda had done this all to save her "sons" to be used as weapons and tools by the Emperor, a decision driven by maternal love by redirected in such ways that it would benefit Chaos. The Emperor in memory of their time together and past friendship did not kill Erda but he did Banish her from the fledgling imperium as he worked to salvage the situation and ready the newly made Space marine legions.
Thus began the Era of the Great Crusade to not only unite the fragmented remnants of Mankind under one banner but also to retrieve and reunite with the Primarchs.
Yet unbeknownst to either the Emperor or even the Chaos Gods, someone had intervened and merged a new soul with the Second Primarch as he along with his brothers travelled through the Warp to reach their soon to be home worlds.
No one knew that this one act would change the destiny of one of the future Lost Primarchs in ways not even the Changer of Ways could foresee or even the Emperor could predict and thus once again ripples were made on the river known as fate.
The Being in question only watched after his work was done as he cleaned his hands and looked behind him beyond space and dimensions to his partner in crime.
