While wandering Mombassa Streets last night, I noticed a trend that I'm sure many of you have noticed as well, glyphs seem to have different levels of significance. For example, the two types of glyphs with symbols in all three areas seem to be the least significant, as they never seem to change, and are often found near audio logs and weapons. The next level up, are the glyphs with one SI face and two symbols, I put them one level higher than the basic symbols only because they are unique, of a limited quantity, and are only found in one area. I don't yet know the significance of these glyphs. I think the most important level of glyphs is at the moment the blank 'Y' glyphs (I call these reactive glyphs, because of the role they played in opening the secret door). These are the glyphs that really catch my attention, as they are always found in the presence of dead elites, and can be found all over the 'Squidhenge' obelisks. I also include the 'sad' super mono-glyph in this category. The final level of glyph includes the mono, di, and tri super glyphs. Because of their tendency to appear and disappear when as yet unknown criteria are met, I call these indicator glyphs.
So:
Level 1: Directive glyphs, not really important for the solving of this puzzle.
Level 2: Directive SI glyphs, Importance unclear, but worth investigating.
Level 3: Reactive glyphs, seem to open locked doors or act as triggers for events, very important.
Level 4: Indicative glyphs, seem to react to unknown criteria, should be closely watched.
This is of course all speculation, I'm just using the trends I've noticed while investigating to categorize these glyphs into levels of importance so that they can be more easily studied. I'm also sorry if I've made any errors or repeated any information, but I felt I should share my observations.
