Mm, that depends entirely upon your reality. Canonically, she could meet you nigh anywhere within the established world, though she lives and breathes the heart of Manehattan. Philosophically, the topic could be of any design, for I'm aiming at you. Yes, you, the writer. I want you to consider the full scope of the life held under the weight of your pen. I want you to reach into the recesses of your character and from the depths discover elements you've yet to develop in any other work. It's limiting, surely, what few stories we write, in truly coming to appreciate and live within our characters. Some often go quite underdeveloped, being good only for a one-off of superficial consequence where nothing of merit is gleaned. Should there be anything you've wished to explore with your character, be it physically, emotionally, morally, what have you, there's undoubtedly a thread that can tie us together. And if you wish it to be a story that bleeds into your character and their other works, current or future, that would be a treat. In fact, that's rather the idea.
On the whole, I'm hoping you'll humour me in delving into Aria's bitterness. I've written plenty a page where she's a confident, sassy mare beyond compare. You've only to ask @Randimaxis , the site's second best writer and her best witness, for the evidence. But I lost a part of myself a long while ago, and so, in essence, has Aria, but I never fully explored what that means for my past, present, or future. And so after these many years, she has grown as stoic as the callouses on her professionally trained hooves and deaf to the beauty of her notes. She shan't be a complete bore, I hope, but perhaps not as lively or considerate as one might like. She'll put your mettle to the touchstone to find some trace element of herself in you. It might even feel like an interrogation, or cynical therapy at points. But she's looking to establish a connection. What your character is looking to derive from it, I leave entirely up to you. As for the reason, perhaps they simply enjoy classical music. Mayhap they're writing a story on the arts. Should you need a prompt to get the ball rolling, I'd be more than willing to provide one. She's well-studied and well-travelled, so excuses to run into people are plentiful.
In summation, yes, deep philosophy is on the table. Not primarily within or about the lore of the show, although that can still be discussed if that is an element of your character you'd like to explore. I would like us to more or less live the experience of our characters. Or, if it's easier, impose your will upon your character to see how you'd like to develop them. You can consider it a roleplay like any other, if you wish. Perhaps even frame it as SoL, if its easiest. Just mind that there is no overarching plot or end goal. There are no winners or losers. Simply an endearing chat with an old soul with a cup of cocoa on the side. If you'd like to help world build, you're free to do that as well. If you'd like me to create the world in its entirety for you to play in, that's also perfectly acceptable. If at any point you believe our discussion could do with another friend or two, I can change it from a 1x1 no questions asked, although I do prefer the intimacy of just one other person in soul searching. Just some things to keep in mind, if you're still intrigued.
Perhaps it would be best for me to write a sample opener so one might get a better sense of the world into which they're delving.
