On Edens origins

While doing the MSQ I mentioned to myself that Chthonic Riddle, Therion had some design aspects that reminded me of Eden... Most notably the purple domes, did anyone else get this vibe at all? If Therion was the result of Ancients Creation Magic running rampant, I wonder perhaps if Edens creation is rooted in a similar manner? We know the Flood of Light was part of the Acians plan, and if that Flood was being caused by the First Sin Eater, perhaps the Emet created Eden specifically for that purpose? Given how simple a matter it was for him to hand over a Lightwarden to the old Major of Eulmore, it stands to reason he had some method for dealing with them...

Also worth pointing out, that in our fight with Hades, his wings had clusters of Dark Crystals forming on them. Eden, likewise, has clusters of Light Crystals forming under her wings... Heck, if you attach a giant domed Garden to Hades back (with his wings holding it in place), I think he'd look very similar to Eden in a lot of regards...
