his name is vasko sava and he had a very nice job doing math and making graphs on corpus pillar “the ample profit” until it crashed on deimos, where he survived in the infested ruins of his old ship until he got bit by a maggot. he cauterized the wound with his prova and stopped the infestation from spreading, and when a tenno came through on an extermination mission, it decided to turn it into a capture/rescue mission instead, brought him back to the dojo, fixed him up, and recruited him for his railjack!
