Midas Virus

Background
The Midas Virus is an extremely dangerous techno organic bioalchem viral weapon of alien design. Originally developed by the extinct Seraka as a weapon of final resort during their civil wars, it is self-replicating and self-modifying virus. Rather than target flesh and blood, it infects and corrupts machinery. Circuits and steel mutate and twist into the architecture of it's extinct alien forebearers.

But machines are not the only thing at risk. Those possessing bionics or mechanical enhancements are vulnerable. Whole worlds, Titan Legions, and the Bronze Claws chapter have been infected. Ordo Xenos continues to struggle for a cure, but the only one so far is exterminatus.

Microbiology
The Midas Virus is not wholely biologal. The Seraka were masters of genetic manipulation among other things and they wanted to make a truly terrifying weapon as boast to their skill. Midas is a fusion of nanocircuitry and virus, a nanovirus.

Golden Wars
The origins of Midas stretch back eons to the twilight days of the Seraka Empire. Its golden era was longer over, now its borders beset by invaders and and it's territory fracturing into warring geno-factions. Their vast geno-armies were turned towards eachother and the Empire fracture. Each faction competed in a genetic-arms to produced the superior gene-soldier. Brutal warfare shattered planets and quelched stars to death. In the final weeks of the Golden Wars, terrific and horrify weapons were produced en masse, the Midas Virus was only one of many.

Symptoms
For machines, infection and corruption are swift and near unstoppable. Ordo Xenos does not yet fully comprehend its workings, but Midas is a alchem weapon, it transmutates what it touches and twists it into monsterous and yet hauntingly beautiful forms.

The more it corrupts the larger it spreads until whole worlds are consumed and transform into golden cities and shining alien spires. Those infected become part alien themselves, nothing left of them but a mind just as alien and incomprehensible as their makers.

Biological Vectors
Beings of flesh and blood are also vulnerable to the virus, if they are part machine. If so, then they will be corrupted if it colonizes too far. Ironically, ordinary humans are less at risk while Tech-Priests of the Mechanicus, Titan Legions, and even the Adeptus Astartes are the most vulnerable.
 * Stage I - The initial infection is difficult to notice at first and is first observe in machinery or any advanced form of technology. In bionic limbs the faint patterns of golden vine-like veins are visible under close inspection. These patterns will creep up and become more visible as the corruption progresses. Gradually preformance actually improves for a time, old quirks vanishing and never needing maintence and all damage just vanishing when not under surveillance. At this point it is still possible to save the host if the infected limb or parts are removed.
 * Stage II - Once it has colonized the machinery enough, the Midas will actually jump to the biology of the host. When it progressses this far, it's alchem vectors take hold. Mechanicus Biologists are stumped on how this is possible but it observed what happens. The virus alchemically transmutates flesh and metal into one and its tendrils dig deeper into the host. The host will feel no pain, rather it has been observed and reported that the infect feel eleviated. Members of the Roaring Stars who were infected claimed to have experianced whole new senses never before experianced, among those they could explain were seeing through walls, hearing at different frequencies not meant for human or post-human ears, and many others. It has been theorized and confirmed the Space Marines will actually meld with their armor's auto senses, along with the rest of their armor. Symptoms also include hair loss and behavioral changes, simple gaps in logic and sentences or subtle changes in mannerism.
