I still do not know what it is and to be honest I do not care anymore. After the deathstar comic where black in black numbers were done I kinda stopped looking for them serious.
If you hide them well -> cool, numbers in a box full of numbers -> alright as well, but to be physically unable to see them that is just not hiding anymore thats cheating and takes out all the fun of searching.
Sorry Larian that was waaaay overdone.
