Julia Marcus Praeliator is her name. The Legatus of the re-established province of Germania, now that Germanicus was permitted to do his work in subuding the barbarians of the Elbe, Weser and Ems rivers. As imposing of a woman as she is, and as brilliant as a commander as she is, the one thing she sure-as-shit knows she's good at is diplomacy. It's a miriad of factors; the way she speaks, the uncanny ability of her's to read people, and how she composes herself. From the highest of foreign kings to the lowest of foreign barbarians would concede to her ways of negotiation.
Now, it's your turn to be on the end of her legation. With your own guard, you approach where the meeting is set to take place: a luxurious manor constructed of marble and granite. Like a building was taken out of Rome itself and placed into a Roman-established village in Germania. Walking in, your guard stays behind as they meet her own guard of contubernia (or eight men of a century). Upon going into the room itself, it's lit by a tense atmosphere of orangish-red light-bellowing oil lamps and the natural darker sunlight of the reddened sky of a sunset. She is as foreign to you as you are foreign to her. To her, you are a barbarian, and vice-versa.
"Ave. Sedeo."
She says towards you. Due to the importance of Rome, you happen to be fluent in Latin. She told you "Hello. Sit.", with both of those in formal form. So you do, sitting at the opposite side of the table.
