I do have one or two clarifying questions to OP— namely about this Grand Duchess Svetlana you’ve created.

Is Svetlana Garlean? And more specifically a member of the Galvus family? Because I’m pretty sure every Garlean other than Cid (and Midas which is a Greek name) have Latin/Roman names. Svetlana is a Russian name, and while certain aesthetics of the Empire are Russian, wouldn’t it make more sense for her to have a Roman name, especially if she’s a member of the royal family.
