Revelations from EE3:
-Forgiven Obcenity *WAS* formely the singer who was punished by Vauthry in MSQ.
-Omicrons were the strongest beings in the universe after defeating the Dragons (what does that say about us having dunked their strongest weapon?)
-Avatars are the 13th reflection of their Reaper's soul. This might contradict Golbez being our 13th reflection, which is all but confirmed, given how their shadow "comes out" of us during Lunar Subterrane dungeon and their face is never shown and they are suspiciously unvoiced in a voiced cutscene....
-Memories of Vauthry were partly included in the summoning of Fatebreaker. Many people assumed it was just Thancred/Ran'jit/Gukumatz, but the Light aspected cycles always reminded me of Vauthry.
-Garlean Legatus armor have inlaid crystals with the hopes that they would store their memories for future use (like rudimentary job stones). These are implied to be the stones that were employed in the 2nd Generation Anti Eikon Warmachina series' Synthetic Auracite System.
-Venat's group stole the "Deity" concept from the Bureau of the Architect to summon Hydaelyn, which was formely used in the summoning of Zodiark. This implies that the concept crystal for "Deity" may have been something the Words of Lahabrea submitted to the Bureau for testing and approval following the events of Pandaemonium. In other words, Athena's research may have directly laid the groundwork for Primal summoning. The other deduction of this finding is that the enthralling power of Athena may have inspired Lahabrea down the line to employ similar techniques in the corrupt version of creation magic he gifted to the Beast Tribes (which ensured their Primals would enthrall their summoners). Meaning this effect might be tied all the way back to some property or quality of the Heart of Sabik/Ultima's Auracites?
(to give an in-universe reason for some monsters using similar models)
-During the Flood of Darknesss, people's Souls intrinsically remembered a similar world-ending calamity (Final Days) and some souls were twisted with the memory of those creatures (Terminus Detonators), explaining the similarity between the two
-Svarbhanu (the first blasphemy) greatly resembles The First Beast. Certain primordial fears are "burned into the very soul" so this is no coincidence.
-Similarly, the Indigo Beast Blasphemy likely resembles Archaeotania because Archaeotania was Beast of the Final Days that resided in the sea and the soul remembers?
