The Erasmus began as a Lanza class corvette, which was commissioned by the Mars Security Division. The crew of thirty were transporting an experimental nanite weapon for the Martian Navy when it was released on board the gunship. The entirety of the crew was deconstructed on a molecular level by the micro machines into airborne particulates rendering the gunship empty. After the nanites completed their tasks they succumbed to their programming and deconstructed themselves leaving no trace of themselves or the crew.
The Martian Navy commissioned a rescue attempt by employing the original manufacturers of the ship. Vander Air & Space Corporation sent out a small retrieval team, which upon discovering the state of the ship, rendered it operational. VASC special forces reprogrammed the transponder to read as a VASC prototype under classified solar system wide operating contracts.
VASC reported the ship as destroyed and offered doctored evidence to the MSD as proof the ship was indeed destroyed by parties unknown but hinted heavily it was the work of the Earth Forces. The Martian Navy trusted the review and wrote the ship off as lost, meanwhile VASC continued to operate the Erasmus with a small crew for its own covert operations within the system.
To this day the Erasmus is known as a VASC prototype vessel which operates within the system as a privateer and picking up contracts among the system. The crew and ship are loyal to no planetary nations, operate outside of corporate law and is viewed as a necessary evil. While they are tolerated they are by no means legitimate or allied with the greater nations of the systems.
The gunship remains formidable but it has its limitations and while news of the crew and its exploits are spreading across the system, the threat of war between the inner planets and outer planets have grown exponentially. Should full war break out within the system these tolerating nations may force the crew to pick a side or they may become another enemy of system wide control.
