The Exploration Facilitation Force (EFF) was founded at the end of the twenty-first century as the frontline for world exploration and settlement. The Force is highly trained, but as the saying goes: "you cannot prepare for everything." Because of this, the EFF has the highest casualty rate of any galactic unit. The training is hard, the job is harder. Because of this, the men and women of the EFF generally refer to it as "the EF'ing Force."
Although any advanced class may be found among the EFF, the most common is "space monkey" as found in the D20 Future core book.
