Uhhh, point by point I guess:
[quote]I was pretty much fine with your character until you pointed out that you ported it from a video game.[/quote]
Ophanim in-game is mostly mechanics and theme, with exactly one lore blurb, shown in the picture. Everything that makes it more than that was me.

[quote]I would ask that you personalize them a bit more? Maybe introduce more of a personality to help them interact with their fellow Archons? Otherwise they may have difficulty cooperating with your 40-million-year-old "elder spirit."[/quote]
I think its inhumanity is pretty core to the character I want to play. Its age and origin are just aesthetic (it's spent the overwhelming majority of those 40 million years in an unchanging world devoid of unique experiences to develop from, so practically speaking the extra zeroes are only there to sell the Lovecraft look), but I'm not willing to make this character into the sort of entity you can have a normal conversation with. Not to say that it can't talk to another Archon, but it wouldn't be very charismatic.
The "(very alien being) obsessed with the trappings of divinity" thing is The point. If that won't work, I have other ideas I can try to put to a sheet, no issue.

[quote]Have you considered maybe that they might have been human to start, until learning the "truth" within the Book of Light?[/quote]
I could make that change, or something similar, but I wouldn't want anything to be left of that human.
