In this chapter, the Time Traveller explains how he is able to travel back in time by using a device called a "spatial anomaly" . He explains that the time machine is like a "portable space" in that it uses "spatial anomalies" to achieve the same effect. The Time Traveller wonders why he is robbing the family of Ulysses. He wonders if there is a better place to live than the one in the house of Ulysses. He also wonders if he is forcing him to do something "more interesting" than what he is doing. He asks if he should open the tomb of his true ancestor. He then wonders if the symbols on the coffin are referring to the beginning and the end of his life. He realizes that he is in the wrong place. The underground building beneath the house is a dozen times larger than the mansion of Barzesa. The time traveller wonders if this is a coffin or if it is just condensation on the surface. The Underground Building is a polished metal structure with a modern emphasis on "functional simplicity." He wonders why there are shackles on his wheelchair. The wheelchair is too "unconventional" for him. The door to the underground building is blocked by a cold door on the table. He has no idea how to open it.
