Just a few questions:
Is there a puzzle at all (does it exist)? There are 4 "buttons" which you can activate, but they do not seem to do anything.
In maradino's library there's 5 books (in order from bottom to top): cold bones, matchbook, stormy nights, devouring greed and rain. May those books be a part of a puzzle(if it exists)?
And finaly - how do you solve it?
