You and Nyx had befriended each other while in the Kingsglaive, both of you having been from areas that Niflheim had taken control over, allowing you two to bond over something. Both you and the other glaive had lost people close to you, making the tight bond between you even tighter, as you both understood what it meant to lose a loved one. Nyx offered to go out with you for drinks multiple times, and eventually began to introduce you to his small group of friends.
