In 2600, Benny encountered EarthFed forces on Goron IV, where they were exploiting native Goronians. The Goronians had the ability to open conduits to other universes, and the Earth Federation hoped to take advantage of that ability.
When Benny ruined their plans, the EarthFed leader, Dr Grobe, was very angry, but she accused them of exploiting the natives and letting her be captured. They left the planet, returning to New Terra. (PROSE: The Door into Bedlam)
