Effcee was a female-programming droid working along with Deeve and Jarsa, two scouts of the Bureau of Scouting and Exploration Services, and traveling with them in the bureau's NRSS Founder in a mission to scout several planets in search of useful resources. While Effcee considered herself an able pilot, Deeve disagreed, and he would rather not have had her piloting the ship. Effcee was also affectionate when talking with Deeve, calling him "honey" and "baby" to his chagrin, even after Deeve had tried to reprogram her to remove these traits.
