I adore the art--the style, the colors, just fantastic. I definitely think we were on somewhat of the same wavelength--mythic verses (in haiku) of an ancient civilization, horrible universe-ending monsters. Good stuff. I also really like the Obelisk Dice mechanic--a visual representation of a ticking clock is just the kind of prop I like.
I could use a smidge more flavor from the font, though I'll totally concede it's quite readable, and I think some of the text could use a light copy pass (for example, in the Star Presence section: "As it begins to take form all present would see pulsating veins and stygian viscera take shape before them." The repetition of take form/take shape felt like it could be streamlined). But all of those are nit picks. I really like this module, I'd love to run it, nice work.
