The nearest transport terminal was a short walk from the school, at the end of a cobblestone path. It was a large domed pavilion supported by a dozen ivory pillars. Each pillar bore an OASIS teleportation icon, a capital "T" in the center of a blue hexagon. School had only been out for a few minutes now, so there was a steady stream of avatars filing into the terminal. Inside were long rows of blue teleportation booths. Their shape and color always reminded me of Doctor Who’s TARDIS. I stepped into the first empty booth I saw, and the doors closed automatically. I didn’t need to enter my destination on the touchscreen because it was already encoded on my voucher. I just slid the voucher into a slot and a world map of Ludus appeared on the screen, showing a line from my present location to my destination, a flashing green dot next to OPS #0571. The booth instantly calculated the distance I would be traveling (462 kilometers) and the amount my school would be invoiced for the fare (103 credits). The voucher was verified, the fare showed as PAID , and my avatar vanished.
