I'm going to throw a few things out there: 1) I think we need to focus on the origins of the glyphs ie engineers, covenant, other (keeping in mind this group would have some interest in virgil or what's buried under him) 2) what does it mean if a glyph dissapears? 3) What do the symbols in the glyphs mean? (there's only a few different ones, and we have tons of primary sources at our disposal. If you have any of the graphic novels, please scim through them for any similar symbols) 4) at this point we should be forming theories, so give it your best shot, there are no wrong answers. 5) What is the origins of the engineers, and why would they spend their time with these symbols? 6) how could all of these things link together or is there any proof that they are independent occurences? 7) ( I had to end it on 7)
