For the most part, the information in the persona section largely pertains to your persona/when you are ysi g said persona. Though that's not to say that there isn't some overlap, at least after your persona awakens. Example, scrawny nerd who would realistically have a str of 8, generously, may suddenly find himself capable of superhuman feats of strength occasionally thanks to his barbarian persona. But that doesn't mean he can suddenly become an Ace football player if he still never bothers to physically improve his body to match his persona.
Just as well, even if your persona is a genius 20 Int Wizard, that doesn't make the user suddenly a genius capable of using magic in the real world. Indeed the more esoteric skills such as Arcana, History, Religion, and Nature would mostly come from said Persona, as oppose to the character themselves. Though in that instance the Persona is more akin to a computer: it may or may not have the information you seek, but it's still up to the user to make use of that data.
How Persona interacts with their users is something that will be explored IC, so I won't spoil too much ooc, but I do want to make clear that while the personas are an extension of yourself they are also their own entities as well. The more you are in sync with your persona, the more you and the persona basically act as the same person. But when you start going against your persona, funky stuff happens.@Dark Cloud
I'm fine with either variant of the genasi. Just clarify which variant you're using in your character sheet so I know which one I should be referencing.
Things look good so far, but I'll withhold a final decision until everything is complete. Question though, did you make up your own Background it just reflavored the hell out of the strange student background? While j don't mind reflavoring, please keep the mechanical bonuses such as proficiencies, items, and background feature the same.
