Editing Life Bringers (section)

=Naval Forces of the XIIth Legion=

The fleet of the XIIth Legion was of great importance to its main strategy of orbital assault. The Life Bringers converted a number of ships to suit their various ends. Roughly 100 escorts were converted for the transport of the wounded and diseased, these ambulances were equipped with a number of advanced life support technologies. Others were turned to less benevolent ends, many of these ships were utilized in the mass deployment of the horrific toxins of the legion. Even larger ships, such as the cruiser ''Man's Cure'', which famously poisoned the entire population of the heretical hive world Qinn with caustic Zobyn gas. 

Johannes Vrach sought to exemplify his values in each part of his legion, so some battle barges functioned as dedicated research stations or hospitals. Many times these were left to oversee particularly difficult epidemics away from the bulk of the fleet, dedicating themselves entirely to their research. Besides these few notable exceptions, the Life Bringers maintain the remainder of their spacefleet in a fairly conventional manner. Though the legion started with a larger than average number of ships, the reckless nature of their tactics as the Brothers of Death led to the loss of many ships, including their original Gloriana-class battleship. At the time of the Heresy the XIIth legion had 20 conventional battle barges, with 8 being turned to research and applications, as well as 26 battleships. At this time, the Life Bringers also held 244 light cruisers, 87 heavy cruisers, 112 destroyers, and 784 escorts turned to various ends under their control

==''Valetudinarium''==

The massive vessel which acts as the flagship of the XIIth legion is unlike those of the other astartes fleets, being an artifact of the Dark Age of Technology. The ship itself is monumental and, before the discovery of the legion's primarch, utilized its unique and powerful weapons systems to devastate many planets with initial bombardments. The ship was repurposed by Johannes Vrach to suit his own ends, eventually becoming known the largest and most advanced medical research and treatment facility in the Empire. Though it does still have formidable offensive and defensive weapons, the Valetudinarium is never willingly brought into the fire zone, as it's purpose as a center for scientific work is paramount to the primarch.

The mammoth ship contains city-sized wings dedicated to curing the many diseases which afflict mankind, these hospitals are the front line in Johannes war against disease and are constantly abuzz with activity. The genetic engineering labs of the High Genetors which maintain the legion's gene-seed are second only to those of the Emperor himself, their research into designing hardier and more useful life is unique among the legions. Biochemical weapons labs are constantly at work developing new and more efficient ways to eradicate the impure, the nightmarish scouring compounds and tailor-made viri that the Life Bringers employ are developed here.
