Fleet has discovered a planet rich in Manzakium, an element that enables travel between the stars. They built an orbital space station at no small expense to aid the rapid colonization of this pristine new world. They established a colony within a protective dome to both mine the valuable ore and terraform the planet, transforming it into a new home for mankind. ...and then a transport ship from the orbiting station arrived covered in some strange grayish dust. The dock workers became ill and were immediately quarantined. The colony doctors were puzzled, but determined that "...it must be some new form of fungus..." That's why we called you.
