Liam survives Resson. And Xaden has a little sister who is a year younger then Violet. And maybe she was fostered super far away from everybody else, so no one has heard from her in like, seven years.
Maybe she was fostered by an ex assassin, and he trains her, and she joins the guild of assassins and becomes like one of their best, most lethal assassins. And she goes about pulling strings behind the scenes and hunting down venin as revenge for her dad.
And she keeps a loooooow profile in Basgiath, like keeps her guild mark covered at all times and stuff (could also be in a different wing completely, so that helps her hide her extracurricular work).
And, obviously, Xaden and everyone else is busy with their own things, so she kinda goes months without interacting with the others. And her dragon is like, 'f*ck the empyrean, we are going to hunt venin and wyvern on free weekends and in the middle of the night.'
Maybe in Iron flame when everyone defects she doesn't show up at Riorson house, she goes off and like, does a bunch of missions for the guild and kills off the last of the venin and is gone for a few months.
And Xaden is a wreck cause, 'I was super neglectful and idk where she is, and what if she's dead?'.....just stressing out cause she's gone and so are the venin and what's going on?
And she just shows up randomly dressed in her assassin uniform mask and all, with the head of the head honcho venin all just drops it in front of the assembly and is like, 'wars over stop being so broody' and takes her mask off.
And Xaden can be all like groveling for forgiveness that he didn't speak to her for like, eight years and all that. And just, the crew having to deal with a super in demand assassin and all her unhinged friends she has made in the guild and all the people she has helped over the years that love her. Maybe she pulled some strings and got Tyrrendor a bunch of alies and has gotten the king to reinstate Xaden as Duke. And when she shows up she's like, 'sup bitches, I got responsibilities for you all.' And Duke Xaden has to deal with all these foreign people who are now alies with him coming and asking to see and flirting with his sister in languages none of them but her understand. And he's just a bit overwhelmed and very overprotective.
Maybe Xaden and her spar, and she just beats him into the ground so fast and he kinda has this realization that 'my baby sister is all grown up and has seen shit even i can't imagine' and just has a whole lot of respect for her. Maybe they have a heart to heart and he hears about all the terrible things that happened to her since the rebellion and just, like, realizes that she really is all grown up and has her own scars and has lost her own people and he needs to start treating her that way and he can't really treat her like a child anymore.
