Varric doesn't give you the nickname Rook, your whole faction calls you Rook. It makes no sense to give you a faction specific last name and then your faction doesn't even use it, but yeah.

Hi hi!

This will be a bit of a ramble, sorry.

Varric, as a character, gives nicknames to those he's around for any length of time. (Solas is Chuckles, Merrill is Daisy, Vivi is Iron Lady, etc. Very few people in close contact with him will escape earning a moniker. I can go on about how I think it's one of his ways of telling people he sees them, but I digress.) The player character has been traveling with him for a year/the better part of a year. Varric would have definitely given them a nickname in that time. (Honestly it shocks me Harding doesn't have one by now but maybe he tried and she shut that down like Aveline once did lol) When you're putting out your things in the Lighthouse one of them is his shaving mirror and you have a moment of reflection about what he said when he hands it to you. There's also the whole time where he's giving you advice and guides you (IYKYK) and it's clear he means a lot to a Rook and they're close.

That is to say, no matter what faction you were with, you left in disgrace. You broke some code the higher ups held dear, messed up well laid plan, ignored orders to save people, etc. You didn't "fit the bill" for your faction and were summarily "adopted" by Varric to help in his hunt for Solas. Those things that made you a bad fit for your original faction? Made you perfect for what he's doing. A good person that doesn't let the potential costs stop them; they see what needs to happen to help people and will run head first into it and manage to figure a way through the most fucked up situations possible.

When you first meet Neve, you're introduced as Rook. "Like the chess piece?" Yes! One of the most powerful pieces on the board, "but tends to think in straight lines". Which becomes evident in all our shenanigans as Rook through the game. Rook's ability to claw their way through the worst situations and be flexible and creative means that Solas wouldn't be able to predict them or what they'll do. Which turns out to be right; he doesn't expect you to drop a statue on him in the middle of a massive ritual. Rook saw only "this ritual needs to stop NOW" and found a way, no matter the consequences.

I didn't hear that dialogue my first game, though, because I did my first run as a Shadow Dragon. Neve doesn't comment on the naming convention because instead Varric says you both do work with the Shadow Dragons and she just skims past the naming convention to say "Oh, what a coincidence." You are still introduced as Rook at first; it's not until later when you're in the Lighthouse where you can have the conversation that you've heard of each other even though you've never worked together.

Because even if I've worked in the group beside you under the same boss for 20 years, if you're introduced to me as "Rook" instead of "_____ Mercar" I'm not going to know who you are. It's not until later, probably while you're unconscious and she has a chance to speak to Harding, that she says she knows who you are. (Based on what Bellara says when you find her in the forest, you've been out cold for two or three days. Can you imagine what our detective figured out in two or three days?)

All that to say, if "Rook" was given to you by the Shadow Dragons, Neve would have said "Oh! I heard of a Rook." instead of just "Oh! What a coincidence we're both Shadow Dragons." She doesn't comment on who you are and what you've done until later when you have a chance to talk to her in the Lighthouse.

And throughout the game, you continue to be introduced as Rook. Even if you started as another faction, if you're written a letter about "Rook" and not your real name, why would anyone know who Rook is until they meet and go "Oh this lil shit right here. I know this asshole."
