Or maybe, the proto-excal description, along with nemesis nyx is just a reference to Dark Sector game, and you looking for lore where it doesn't suppose to be in the first place.

I know, that the sole fact of proto-excal existance was the reason someone made that huge textwall of lore speculation on this wiki some time ago, connecting Warframe to Dark Sector universe, but its all became irrelevant with Second Dream quest. So yea, you looking way too deep, man.
