This virus swiftly spreads to anyone invading an [[Ark of Omen]] and causes gruesome mechanical growths to erupt from their bodies and wargear. The growths of some of the infected will then drag them into the fabric of the Ark, while others are transformed into vessels for more Possessor Tech-Daemons.
