The Route of Ages is a space-time portal that can lead to nearly anywhere or when. It takes the shape of a cube within a cube (a four-dimensional cube, called a hypercube or tesseract). It is the place "where opposites cancel time". It is this portal through which Trance Gemini takes the Andromeda Ascendant and her crew. When the Andromeda passed through the Route of Ages, she arrived on a planet of the Seefra System (a future version of Tarn-Vedra), where Dylan Hunt finds out that he is the last of the Paradines.
