Alright, I solved it.
Then I noticed that all the "eyes" appeared a bit "flat" on the top, instead of entirely round.
Then I noticed that none of them had a secondary "animation". This isn't really relevant, since they can't attack - but they can still cast spells, dammit!
So I threw a wrench in it. Then another one. Then I decided to merge it with some of my own mods. Suddenly, I've been stuck for hours doing a whole slew of minor stuff.
Since Psientist seems to have gone AWOL, I felt that there's no harm in sharing.
Read the top of the mytheology4.dm for a full disclaimer on my part.
Changes: Renamed, changed descriptions of and diversified all Great Eyes. Only The Earthen Eye (Earth) is now a natural shapeshifter (into The Aether Eye (Air). Added secondary images for all Great Eyes and made them "rounder". Added my own Ecclesiarch, Spider King, God-King and Sunwell pretenders. Changed the descriptions of Grim Reaper & Wraith King pretenders. Changed all instances of Cuthulu to Cthulhu, including the name of the pretender. Numerous small changes to most of Machaka.
Just thought I'd share. Smack me on the fingers in case there's any complaints.
