Thanks to everyone who posted their thoughts in the last thread. I now have a complete squad to show off.







Some Quick Fluff Notes for those who missed the last thread:
The Valkyries of the Omnissiah are Space Marines. They are modified from regular human females using geneseed just like other chapters, except that their geneseed only works on females. They are not something that "Counts As" Space Marines.
The Background for them is that the two missing legions and their primarchs were female during the great crusade. During the Heresy, they remained loyal to the Emperor, but were nearly destroyed during the conflict.
Rouberte Guilleman was many things. A brilliant tactical commander, a keen administrator, and an immovable chauvinist. With his unique position of power following the heresy, he had an opportunity to reshape the Imperium as he saw fit. There would be no place for female astartes in his new empire, and the survivors from the two female legions were killed, their names expunged from all records, and their remaining geneseed stocks ordered destroyed.
It was only after this display of ruthlessness that the remaining primarchs consented to have their legions broken up into chapters. They could see that Guilleman would go to any length to see his plans implemented.
The story might have ended there, but the Adpetus Mechanicus of Mars have always followed their own agenda. Guilleman ordered all geneseed stocks on mars moved to terra, in order to limit the power of the mechanicus, and commanded any remaining female geneseed destroyed. Under the threat of war, the Fabricator General handed over the remaining stocks of male geneseed, but sealed sealed away the stocks of female geneseed instead of destroying them, into endless vaults of the red planet.
Ten millenia later, The Adeptus Mechanicus of Mars has determined that the Imperium is too weak to survive, and has begun a military build up that will culminate in the destruction of the Adeptus of Terra.
As the determined date approaches, the vaults of mars have been unsealed, and the geneseed of the lost legions is being used, in secret, to create genetically modified warriors that can match the Adeptus Astartes in the coming war.
The Valkyries of the Omnissiah are a shadow force that answer only to the Fabricator General of Mars. Only those highest in the Machine Cult hierarchy even know of it's existence. It's deployment is always preceded by a communications blockout that masks their involvement and limits the possibility of exposure. Nevertheless, rumors have circulated from time to time, and the fear of their discovery prematurely triggering the inevitable war between mars and terra means that they are deployed only under the most dire of circumstances.
A few technical notes:
Their Mark XI power armor utilizes newer materials developed from STC fragments unearthed in the catecombs beneath Diab. Consequently the armor is thinner and lighter then bulky ceremite plates, but provides nearly identicle ballistic and energy wepaon protection.
The basic weapon you see carried is a brace of Ion Pistols. A weapon developed specially for the Female Astartes. While comparable to a Bolt weapon in strength and armor penetration, it is superior in that its power cells can last several years before they need to be replaced. Consequently, The Valkyries of the Omnissiah do not suffer the limitations of ammunition resupply that their male counterparts do.
Female Space Marines have a muscle tissue vastly different then that of a normal astartes. During the development of geneseed, it was found that the simultaneous muscle twitch fiber that had been developed would deteriorate when exposed to the hormone balance in a male astartes, so that part of the project was abandoned, and male astartes were modified to have larger muscles instead. The simultaneous twitch fibers, however, could be sustained in a female astartes hormone balance, and their geneseed still contains this powerful modification. Subsequently, female astartes have comparable strength to their male counterparts, but do not require a large musclebound physique.
Also note that, while Valkyries are much taller then the average human female, they are shorter then their male astartes counterparts, with a much slimmer build.
Enjoy, everybody
