During his trek through the alien dimension in 1947, Indiana Jones acquired the part and used it to open up any portal he found to revitalize himself as staying too long in the Aetherium proved to be too hazardous to his health. The portals he opened happened to lead back to certain locations he visited earlier in his adventure: Kazakhstan, Palawan Island, Teotihuacan, Meroe, and Babylon. Unlike the other machine parts which were lost when the Infernal Machine self-destructed, Indy managed to keep the Tool fom Beyond following the Aetherium's disappearance.
