You are glad to be able to leave the Library behind you, with its twisted ways that you never quite grew accustomed to.

You are fortunate not to have to walk through the light of the false-sun. A vending automaton sells you a permit, and you present it to the metro to be allowed entrance. As you ascend from the tunnels near the central station, the metro station disappears behind you, to conceal itself from any other travellers arriving in Warsaw.
