There have been many rumors saying that Atheon could perhaps be a good guy. I am here to propose my theory as to why this may be true. Let's start by stating how this theory is supported. Atheon is a Vex (obviously). The Vex worship The Black Garden. Specifically, it's Heart. The Heart of The Black Garden is a god to the Vex. The Black Garden is part of The Darkness. Atheon's name is Greek. It is a form of Atheos. Spit that into a translator, and it will ask you if you meant this: Άθεος. What does that mean in English? Godless, Atheistic, or Atheistical. Let's make the connection here. Does this suggest that Atheon defies the will of The Black Garden? The Black Garden is a part of the darkness, so does this mean that Atheon is a being of Light? A Guardian? Probably not. The Grimoire for Atheon states that he has a purpose. He is a conflux of time (as his name states as well). He regulates and oversees the Vex conflux system. If any of this is true, he can't be good. But read the last line of his Grimoire card. [i]"But we must accept that all of this is speculation"[/i] His Grimoire is more than likely true, but what if it wasn't. Here is where my theory comes in. What if Atheon really was a good guy? He could have tried to stop the Vex. The Oracles forsaw this attempt and imprisoned him. That is why he is in the deepest part of the Vault. He is a prisoner, a traitor, and it is his punishment. Let's look at The Templar's Grimoire. [i]"The Templar and the Oracles guard the way into the deeper Vault. Legends say that the Oracles foresee what is to come, a world as the Vex desire it - and that the Templar has the power to shape reality to match the Oracles' design, expunging any threats." [/i] The Templar guards Atheon, to be sure that he is never released. The only one who would even have a chance at knowing the weakness of the Vex. He can shape reality. He created Atheon's 'cell' and guards it. He expunges any threats. Atheon is a threat to the Vex. If we release him, that makes us threats. Let's look at an alternate possibility... Perhaps Atheon is Kabr reincarnated after being killed by the Templar. When you die in the Vault of Glass it says "you are forever lost on the dark corners of time" or something like that. When Kabr was killed he was lost in the dark corners of time and was sent to the Vault of Glass. In the Vault of Glass the past, present, and future are accessible and controlled by Atheon. Kabr was sent into the dark corners of time after being killed. Kabr is now a prisoner of time just like Atheon. Atheon is a prisoner of time and therefore gives some legitimacy to the idea Atheon is a good guy because in essence, Atheon could be Kabr trapped in a Vault of time. My explanation to why Atheon (Kabr)was shooting you as you accessed time is, Vex are trying to separate themselves from time and Atheon(Kabr) is simply defending time from all that try to alter it.
