There is a cave in Moirai crossing that has a secret passage behind some vines. In the passive is nothing of note visually, but if you listen you can hear radio static. My first thought was that it
might be a spectrogram, but as far as I can tell its nothing. As far as I can tell it is also not Morse code.

In the same room as the hidden passage there is a thing on the wall that has a push button prompt. After pushing it, I did not notice anything change. The prompt stays there but I can't push it again.

I don't know what this stuff is about, and trying to look it up has gotten me nowhere. Anyone know any information, or am I (somehow) the first one to publicize information on this?
