Tanya the Living Saint
Matriarch of the Mithril Order
Within her private quarters of a battle tent, the sounds of an ongoing battle could be heard while Tanya is assisted by her battle sisters to put her battle armor on. Heavy it was, but with a little prayer to the so called 'God-Emperor' of Mankind lent her the strength to achieve more than outright overkilling strength to use at her will.
"Feh, unlike Being X that wanted prayer and faith for next to no returns, I have to give it to the Emperor for at least offering me his 'holy' power in exchange for prayer and faith.'
As Tanya shimmied her heavy boots on, all to stomp the communist Xenoes heads in better with, she contemplated how she got to where she was now; Raised within a holy order of battle nuns of all things, Tanya found her calling in putting the axe to the Tau that tried to spread the insipid lies of communism through their 'Greater Good' drivel.
'To hell with how the Imperium is run, All I care is to make sure that stupid race of Tau cease their attempts of spreading their lies about the greater good; it all stinks to high hell of the rise of the Soviet Union and their death count against their own people.'
Tanya doubted she'd see the end of her crusade against the Tau, seeing as how the Imperium has been at war from all sides for the last ten thousand plus years. She was a Matron now, and a living saint at that, ironic that it is to her.
As she finally donned her last piece of armor on, she turned and picked her helmet off from the table to place it on. Most would say she should keep it off to give the propaganda a face to present to the masses, but Tanya didn't live through a second, now third life, to know she needed all the armor she could wear to at least survive this far future of endless war.
While Tanya exited out of her tent, a book sat open written in low gothic at her table inside the tent. In the following years and well past her 'death', the book would come to be known as the Mithril order's codex on how to wage war appropriately. Many battle sisters would treat their own version of the codex with reverence, with the original enshrined and preserved in the Monastery of the Holy Mithril Order.
In the coming centuries after Tanya the Saint disappeared during her campaign against the Tau, a campaign in which an invasion of Tyranids were documented to have come in from below the system she fought in at, the Administratum would afterwards regularly pick up reports of battles against the Tau; During those battles, white light would descend out from the sky and impact into the front lines of the Tau.
Many consistent reports would detail of a war cry shouting, 'Death to communism' Just before the sight of Tanya the Living saint to be seen once more, cloaked in a magnanimous armor of gold and wings that spread out wide as the honored Matriarch cleaves and fought her way through droves of Tau with her bolter and chainsword in hand. With the reports of sightings of Tanya the Living saint, her Mithril order fights ever more fervently against the Tau, and should they see their honored lady come down during their own crusade against the vile xeno, the Mithril Order present at the time would be bathed in the light of their lady.
