Dreams.

I dreamt that Nebok was taken on an expedition outside the city as part of his biology training. Only, Nebok was a woman, and the teacher was too, and the teacher had cat ears. I remember there was a labyrinth in the ruins, with low walls (like the labyrinths in a garden), but this one was made of stone. I remember them finding an item called Permadez (yes, with a spelling error). Nebok was scared that it would kill him right away, but it turned out to be just a tube of paste that you have to shoot at cats (???), because this paste neutralizes them. There were a lot of things in the labyrinth, including clothes, but everything was completely stained with something, maybe this paste, maybe something else. In the end, Nebok and his cat-girl managed to find something that wasn't stained, which was the goal of the trip. At the same time, Ples was in the ruins; he had a book (?), which he found in the ruins. Although Nebok and Ples were in different parts of the labyrinth, they could either communicate or observe each other's progress; in any case, Ples seemed to be commenting on Nebok's findings, but again, this is not entirely accurate.
