About the Island[]
Three Mile Island is a historical location on Earth, infamous for a catastrophic nuclear fission incident. Once a site of nuclear power generation, it was the location of an "incident" that permanently turned Terrestrial opinion against fission as an energy source.
By the era of Settler expansion, the location had been completely erased from maps and was universally avoided by both humans and robots, considered a place of ill omen and the quintessential symbol of the dangers of fission. Subsecretary of Energy, Sophia Quintana, identified it as the likely secret base for the humanoid robot that attempted assassination, deducing this from the robot's dying utterance of the word "mile" and its connection to fission technology. R. Daneel Olivaw and R. Giskard Reventlov traveled there with Quintana to investigate, confirming it as the secret operational base for the Solarian-sympathizing Earthfolk conspirators.
