I didn’t have any bias when playing this, and I definitely steer clear from the usual Bethesda hating bandwagon, but this DLC was so lackluster and disappointing that it’s no wonder I completely missed the two new minor companions from the DLC, specially since it wasn’t added to my misc quest log to meet and hire them, so I was none the wiser. I’ve edited my comment to reflect this.
All the Constellation companions get absolutely mad at you and will stop being your companion the moment you try to do something that’s not lawful good, as Bethesda loves to railroad people in this path. It’s quite annoying since the Crimson fleet questiline is one of the best (best as strictly comparative) in my opinion, and your companions will go batshit insane against you if you follow that path.
