Crackpot theory: The Warden is Veytharion
They both have similar facial features and glowing white eyes. The wardens face glows a similar purple when he absorbs Ava Jansens soul in the paradox cutscene and his skin looks like its starting to turn into a similar version of Veytharions skin. The twins mention that Veytharion taught The Warden about the dark aether and basically took him under his wing and once The Warden discovered his true name was when he was able to overpower him. Why would Veytharion get so close to a random person who ended up in the dark aether? Why does learning Veytharions true name give The Warden so much power over him? Why does Veytharion even have a true name? What if Veytharions true name is the same as The Wardens and what if learning that Veytharion was The Warden gave The Warden some kind of upper hand against him or allowed him to unlock his true power? What if im insane and just pulled this out of my ass?
