Booker agreed and handed Anna over to Robert. Seeing that Booker was in debt from gambling, Comstock sent Robert to Booker to trade his daughter, Anna DeWitt, in exchange for clearing that debt. With the assistance of Robert, the three discovered Comstock's alternate self in Robert's universe had he remained Booker DeWitt after not taking the baptism, and later had a child. Because he could not conceive with his current wife, Lady Comstock, Rosalind proposed that they could recover a child of his from another dimension, and it would be technically the same. Viewing another Tear, he discovered that if he did not have an heir, Columbia would fall. Unfortunately, repeated exposure to the machine caused Comstock to age rapidly and his genetic traits to dissipate, rendering him sterile. With the creation of the machine, Comstock used it to enhance his status as a "Prophet". Rosalind Lutece then created the Trans-Dimensional Machine, a machine able to open passages, called 'Tears', across dimensions. This person turned out to be a male version of herself, Robert Lutece, and she communicated with him via Morse Code. Upon further experimentation with the Lutece Field, Rosalind discovered that the quantum atom she was observing was also being observed by someone from another dimension. Segregation was prominent in Columbia, and other religions were persecuted. He started a new religion expounding some Christian and American values, but which also contained elements of racism, elitism, xenophobia, and Laissez-faire business practices. Comstock - through a faction known as the Founders - became Columbia's leader. The city travelled around the world to showcase American ideals and glory. The two worked together and created Columbia within the year 1892. Zachary later met Rosalind Lutece, a respected quantum-physicist, who was able to indefinitely suspend an atom in midair - her colleagues referred to the process as "quantum levitation", while Rosalind herself dubbed it the " Lutece Field". The Congress agreed to fund the city, believing it could be a showcase of American exceptionalism. Congress to build the city, named Columbia, to uphold Christian and American values and share them with the world. Zachary said he was told it was his duty to build and uphold the values of this city. At some point, he claimed to have been visited by an archangel, who showed him a vision of a city in the sky. After the baptism, Comstock became a preacher. He emerged a new man, named Zachary Hale Comstock. Zachary Hale Comstock was formerly known as Booker DeWitt, but after the events of Wounded Knee, Booker attended a baptism conducted by Preacher Witting to ease his horrific memories and wash away his sins at Wounded Knee.
