Having learned that a dangerous contagion is hidden inside prototype biotech bound for mass production, the heroes must storm a dangerous manufacturing facility to prevent the spread before it starts! They eventually trace the source of the mind-controlling fungus to a seemingly quiet hospice, where a representative of the local planetary government is visiting. If the heroes don't prevent this agent from carrying the infestation back to their employer, an entire planet could fall! Unfortunately, the heroes' task is complicated by the return of a hidden faction looking to reclaim the PCs to dissect their minds!
