Mysteronz
The first carbon-based lifeforms to land on planet Scran. We caught some gully interplanetary Boom Bap on an air band radio scanner in Autumn 2019, sent out a welcome transmission and built a crudely constructed landing pad. Upon first contact we offered them eternal sovereignty over the realm of man and mastery over land and sea. They just wanted to get high and put out a hip hop EP. No sooner had Parental Guidance dropped than they were gone.
It may take years for scholars to work out what they were trying to tell us. Last seen graffing up moons of Jupiter. They may or may not return.
