The Tome has served no purpose so far, apparently its just gibberish, but there must be a way to translate the translation, perhaps by using the Red Letter Cube thing, as the reverse of pages in the Tome are sides of the Red Letter Cube thing. I know its not much, but it must have a purpose. Further to that, what is the point of the Skull aritfact. Also, I noticed something, I think the markings on the floor are actually an infinite symbol, but I could be wrong.
I think the artifacts might just be useless. The skull has no use (so far) same as all the others. I think the writing and number cubes are just like, what the inhabitants of the world use (or used) to write as they contain the shapes to write any letter.
The tome could be the exception though, it's the only thing in the game that doesn't translate right.
long shot, but considering the fact that the number 1 seems to be in the middle of the 2nd circle, maybe we need to do the input from the classroom from the neon world again? kinda a long shot but never know
i was hesitant to buy into the tome thing, but the fact that the button sequences are (all?) 8 sequences and there are 8 pages makes me optimistic. maybe there is some translation for the big letter pages (it would explain why they're repetitive if they have to = buttons)
