Cesar couldn't help but notice the change of tone from the heretic that must've probably been perceived by others who were solely focusing their attention on him. By the looks of it, the last period, The Fixed, is the most dangerous period the group will probably encounter.
The heretic soon explained why it was the case as he informed with a sigh, "I like to call it a Fixed Period since after landing the paper floor, one will have to force themselves to remain fixed on their position as the Library isn't done yet with its modifications. Oh right, why did I say the library will be your enemy? Very simple too honestly,"
The heretic gave a comparison, "For example, you are finishing an important work and an annoying fellow decided to be a pain in the ass, that's how I described how it works. As long as the library isn't finished, remain in your position. An indication of how this period will end is the 'closing roof' on the 'current above' of the library."
