Far Beyond the Reach of Earth
Exsurgent Virus Stains
Exsurgent viruses are strains of mutating virus that can infect both digital and biological systems (so a single strain can infect both computer systems and biological life, and can often travel between them via multiple vectors). Spread widely by the TITANs during the Fall, there has been some speculation, especially amongst xeno-deists & techno-creationists that it was the TITANs own earlier encounters with the x-viruses that caused them to seek their singularity, and set them on their mysterious task to mass-upload human minds before fleeing the solar system. In XD theory, some sort of ancient and powerful ETI spread x-viruses around, for an unknown purpose. In TC theory, this was essentially a test that transhumanity failed, proving ourselves not ready for ascension.
Any proof of these theories has yet to be offered, although some TITANs seem to have succumbed to various strains themselves during and after the Fall, suggesting that they did not have full control of the strains they were spreading (though this could merely be another example of self-improving weapons run amok, similar to the TITANs themselves). TITAN relics containing active strains are still semi-regularly recovered, usually with terrible and horrifying effects.
