the glyphs dont correspond to an exact chamber, but rather determine where you'll go next from where you're currently at.
spoilers ahead for anyone who wants to go in blind
----
the first glyph after gather, "rise," is basically a +1, so if you're in chamber 5 you'll go to 6, from 6 you'll go back to 1, etc. if you're struggling, try just using that to cycle through the chambers without having to retrace your steps too much.
the other glyphs i'll leave to you to figure out.
as for the skulls, they only appear in one chamber at a time. their current location is shown by the flaming spears in the entryway. for example, if four are lit, the skull is in chamber 4. once you find a skull, it will have a row of lights below it telling you what chamber to seek next.
hopefully these tips will help you or anyone else get through it. its a challenging puzzle and stumps a lot of players. lmk if you need more hints and i will provide
