Homebrew concept, Clonegrims followers
Basically they are marines who recognized Fabius Biles “perfect clone” of Fulgrim as their primarch, and believed he could restore the legion.
He grabbed 8 of Flavius Alkenexs marines including an apothocary, and gave them genetic material to eventually repair the damaged/corrupted gene seed. After they set off, 4 of the 8 fell back into their desires and attacked the others, managing to kill one, leaving the crew at 3 men.
They mixed Clonegrims genetic material with the gene seed, and over generations of marines it got more and more stable eventually in the 41st millennium being near identical to the original 3rd legions stock.
They use the newer less mutated marines to negotiate supplies and support with lone imperial planets, disguised as a chapter called the “Violet Suns” though they only change their name and symbol, and only around allies. They try to avoid imperial forces as much as possible, being especially careful of the inquisition, with whom they’ve had some close calls.
They basically roam around their region of space picking fights with slanneshi warbands and offering them to join or fight, but pretty much nobody joins, at least not at first. In the current day, the warband is around 700 strong, with about a 6th of them still having traces of chaos corruption/mutations that is not enough to be culled.
The warband tries to live up to the perfection that was the phonecian and succeeds in feeling like the 3rd legion, but they have to appreciate humanity as is and the human form, so they dont accidentally fall back to slannesh while their primarch is held captive by Trazyn the Infinite
Could this be a possibility? Is this lore friendly?
