History of Old Chicago

Old Chicago is a location where Aisha, Reed-7 and Shayura pursued an unidentified entity. The creature lured them into the tombs beneath the city, and their fireteam was among the few to survive. Aisha later said they had not really been hunting it. The three later played Trials of Osiris together, and Reed-7 was killed by the Witness during the Invasion of Earth.
