Taking a break from 6th Ed rumor-mongering, I thought I'd work on the fluff for my Judgment Condors Marines. This is an attempt to explain how a relatively young Chapter (with a high attrition rate, being near the Eye of Terror) might be able to field a full Terminator company. Not that I intend to field such an army on the tabletop but my fluff has two such companies working closely with the Imperial Navy, and it's an interesting fluff-challenge.
Calais was a ranking Tech-Priest who ran seminaries for aspiring Techmarines. After a major cortical implant upgrade, he began having visions of STCs from the Omnissiah. Given provisional sanction to apply his visions to the plight of Marines' increasingly rare equipment, he created the Builders: self-contained, automated factories. The first Builder made psychically-attuned crystals used in psychic hoods. The next Builders made Terminator armor suits, high-quality mind impulse units, warm woolen socks and a refreshing lemonade. (Calais was unwell towards the end and died after the fifth.)
The Builders were declared hale and enshrined in the headquarters of the Judgment Condors Chapter for safe-keeping. The Condors eagerly claimed most of the Terminator suits produced, much to the frustration of other Marines. They also enjoyed the warm, woolen socks and made a sacrament of the tasty lemonade.
Then disaster! Fearing what the Builders of Calais could do to their future, the Eldar made a craven assault upon the JC headquarters. They took advantage of the JCs' heavy use of hypnotic conditioning and subverted their programming, causing all the defending Marines to fall asleep with a spoken word.
The craven assault would have succeeded except for Brother Hondo. Crippled from an explosive decompression in a recent combat, he was waiting for implants to repair his ruined ears when the Eldar struck. Unable to hear their evil, he was the only conscious Marine during the assault. Too weak to fight, Hondo chose instead to switch the door labels of the Terminator Builder with the Sock Builder. Reinforcements arrived before the Eldar could destroy more than the one.
The advanced technology was preserved but the Admech were still furious at the loss of the Woolen Sock Builder. As penance, all Judgment Condors now wear itchy polyester socks.
Any comments? Suggested revisions? Anybody curious can google the "Burghers of Calais", a weak inspiration for this fluff. It's an interesting bit of history, though not very relevant to 40k.
